Abstract The paper introduces quantum redshift. By using the quantum structure of the electromagnetic waves, we can describe the redshift. Losing the quanta masses along the traveling in the space is the reason of the decreasing the frequency of the electromagnetic waves. Recursive quantum redshift predict distance of the objects by calculating the z parameter of the waves since they have emitted. Non-recursive quantum redshift is a fast and good approximation of the recursive quantum redshift. The distances in the quantum redshift is less than the distances in the accelerated expansion space theory. The paper provides z parameter of distances between zero and 12 billion light years.

Abstract The paper simulates the losing energy of the electromagnetic waves in a non-expansion space and no gravitational Redshift. We use the distance and Redshift of 93,060 nearby space objects, including stars, quasars, white dwarfs, and carbon stars, for obtaining the rate of losing the energy of their waves during traveling in space. Quantum Redshift disagrees expansion of space and describes Redshift by losing the energy of electromagnetic waves over time. In the Quantum Redshift, regardless of the material and type of the space objects (stars, quasars, white dwarfs, and carbon stars), the Redshift depends on the distance and temperature of the space objects, and the temperature of space. We have used SIMBAD Astronomical Database. We have retrieved this information from almost 2,200,000 records. The objects' temperature is between 671 and 99,575 K. The distance of the objects is between 413.13 and 0.5 (mas). The paper obtains the average rate of losing the waves' energy for different objects in different distances. The results show that by increasing the distance of space objects, the rate of losing the energy of their electromagnetic waves will be decreased. The paper inspires investigating the expansion space theory by the Quantum Redshift.

AbstractIt has been shown recently that the backscattering of wave propagation in one-dimensional disordered media can be entirely suppressed for normal incidence by adding sample-specific gain and loss components to the medium. Here, we study the Anderson localization behaviors of electromagnetic waves in such gain-loss balanced random non-Hermitian systems when the waves are obliquely incident on the random media. We also study the case of normal incidence when the sample-specific gain-loss profile is slightly altered so that the Anderson localization occurs. Our results show that the Anderson localization in the non-Hermitian system behaves differently from random Hermitian systems in which the backscattering is suppressed.

Abstract. The unique magnetic structure of the terrestrial aurora as a conduit of information between the ionosphere and magnetosphere can be utilized as a laboratory for physical processes at similar magnetic configurations and applied to various evolutionary phases of the solar (stellar) system. The most spectacular heliospheric abundance enhancement involves the 3He isotope and selective heavy elements in impulsive solar flares. In situ observations of electromagnetic waves on active aurora are extrapolated to flaring corona in an analysis of solar acceleration processes of 3He, the only element that may resonate strongly with the waves, as well as heavy ions with specific charge-to-mass ratios, which may resonate weaker via their higher gyroharmonics. These results are applied to two observed anomalous astrophysical abundances: (1) enhanced abundance of 3He and possibly 13C in the late stellar evolutionary stages of planetary nebulae; and (2) enhanced abundance of the observed fossil element 26Mg in meteorites as a decay product of radioactive 26Al isotope due to interaction with the flare-energized 3He in the early solar system.

The Waves

Weyl has shown that any gravitational wave of small amplitude may be regarded as the result of the superposition of waves of three types, viz.: (i) longitudinal-longitudinal; (ii) longitudinal-transverse; (iii) transverse-transverse. Eddington carried the matter much further by showing that waves of the first two types are spurious; they are “merely sinuosities in the co­ordinate system,” and they disappear on the adoption of an appropriate co-ordinate system. The only physically significant waves are transverse-transverse waves, and these are propagated with the velocity of light. He further considers electromagnetic waves and identifies light with a particular type of transverse-transverse wave. There is, however, a difficulty about the solution as left by Eddington. In its gravitational aspect light is not periodic. The gravitational potentials contain, in addition to periodic terms, an aperiodic term which increases without limit and which seems to indicate that light cannot be propagated indefinitely either in space or time. This is, of course, explained by noting that the propagation of light implies a transfer of energy, and that the consequent change in the distribution of energy will be reflected in a cumulative change in the gravitational field. But, if light cannot be propagated indefinitely, the fact itself is important, whatever be its explana­tion, for the propagation of light over very great distances is one of the primary facts which the relativity theory or any like theory must meet. In endeavouring to throw further light on this question, it seemed desirable to avoid the assumption that the amplitudes of the waves are small; terms neglected on this ground might well have a cumulative effect. All the solu­tions discussed in this paper are exact.

Mobile phone became almost essential part of daily life for all generation of people. It functions with the help of transmission of electromagnetic waves from towers to the cell phones in the micro wave frequency region. The energy carried by the waves is not only useful for mobile communication but also produce adverse affects on the users' health as well as to all living beings which are in the radiation area. The paper aims to discuss some of the possible dark side of health concern by the usage of cell phone and radiation from the towers. It also aims to suggest the possible remedies to minimize the health problems.The Himalayan Physics Vol. 4, No. 4, 2013 Page: 51-59 Uploaded date: 12/23/2013

Electromagnetic wave propagation along the interface between a magnetoactive plasma and a metallic screen is investigated analytically and numerically. It is shown that the waves have a Rayleigh character: they are superpositions of two partial waves. It is concluded that electromagnetic waves propagate only at frequencies lower than min (ωp, ωc), where ωpis the plasma frequency and ωcis the cyclotron frequency. The field topology is found, and the physical character of the waves is discussed.

The Waves

The coupled propagation of two electromagnetic waves in plasma is studied to establish the conditions for induced transparency. Induced transparency refers to the situation where both waves propagate unattenuated, although the frequency of one (or both) of them is below the plasma frequency so that it could not propagate in the absence of the other. The effect is due to the interaction of the waves through their beat, which modulates both the electron mass and, by exciting longitudinal plasma oscillations, their number density, and thus the plasma frequency. Starting from a relativistic fluid description, a dispersion relation for plane waves of weakly relativistic intensities is derived, which takes into account the polarization of the waves and the nonlinearities with respect to both their amplitudes. This serves as a basis for the exploration of the conditions for induced transparency and the modes of propagation.

The propagation of electromagnetic waves in a plasma-filled cylindrical waveguide in the presence of a constant external magnetic field is investigated using warm plasma theory. It is found that the waves cannot be separated into transverse magnetic and transverse electric modes; only hybrid modes are propagated. Dispersion relations are derived for zero, finite and infinite magnetic fields. Frequency shifts for the wave propagation in the case of a small magnetic field are calculated.

Electromagnetic Diffraction

The problem of diffraction of time harmonic, electromagnetic waves by a circular aperture in a perfectly conducting, plane screen between different media is considered. In this investigation, the incident wave is a plane wave travelling in a direction perpendicular to the screen. A Hertz vector formulation is used to reduce the electromagnetic problem to a system of scalar problems, which is shown to be governed by a pair of simultaneous integral equations of the second kind. The integral equations are valid for all wavelengths and are especially useful when the waves in both media have long wavelengths compared with the radius of the aperture. Low frequency approximations to the tangential components of the electric field in the aperture, the transmission coefficient, and the backscatter coefficient are obtained.

Acceleration of electrons in the field of two electromagnetic waves propagating in a slowing down medium in the direction of motion of electrons is considered under conditions when one of the waves propagates with a phase velocity greater than the velocity of electrons, and the other with a phase velocity less than the velocity of electrons. Taking into account deceleration by radiation, we determine dependence of the electron energy on the coordinate along the direction of acceleration. Thus, we obtain the expression for the maximum electron energy and effective acceleration length.
