Microwave radiation enhancement and self-focusing using quasi-stationary electric field in a medium with elongated nanoparticles

Occupational exposure to microwave radiation (MWR) has become an inevi-table part of life. Therefore, it is essential to assess the MWR effect on hu-man health. In this study, we examined the non-thermal effect of MWR from base transceiver station (BTS) on humans' sleep quality. Total 1150 partici-pants of different zones based on distance from BTS (145 from inter-tower/zone A; 256 from 0-150m/zone B; 241 from 150-300m/zone C, 381 from 300-500m/zone D), and 127 controls from the area without BTS installations were included. We recorded the electric field strength at the subject’s resi-dence using NBM-550 equipped with probe EF0-391. We assessed the sub-jects' sleep quality by administering the Pittsburgh Sleep Quality Index Ques-tionnaire. ANOVA revealed statistically significantly higher electric-field strength in zone B and zone A. Participants of all the groups exhibited a glob-al PSQI score less than the accepted median score of <5. This implies that subjects of all groups had good sleep quality. However, a more detailed anal-ysis using the Kruskal-Wallis and Mann-Whitney U tests revealed that the participants of exposed zones (except zone D), females, and residents of the 1-5y group had decreased sleep quality compared to control, males, and subjects of >5y group, respectively. From the above findings, it can be con-cluded that the MWR had little effect on the sleep quality, but it does modu-late sleep parameters within the accepted range of good sleep quality as a function of the zone, gender, and year of residence. However, extensive studies involving more BTS are desirable to validate the above conclusion.

The paper presents the results of analysis of electrical measurements performed in the space experiment "Impulse (stage 1)" on the Service module of the ISS RS. This experiment investigated the effects of the interaction of the charged component of the ionosphere to the surface of large KA, which is the ISS. This paper analyses the measurement of quasi-stationary electric field and current leakage, was, respectively, sensors of the vibration type and flat probes from the Complex control electrophysical parameters (CCEP), developed by SPJ MT. To study the dependence of measurements from the ionosphere flow direction to the surface of the ISS RS was installed two sets of sensors with the direction of the angle of "visibility" in the Nadir (towards the Earth) and to "satellite footprint " (against the velocity vector of the ISS). Carried out analysis of common regularities measurements depending on the sun-shadow environment on orbit ISS motions and depending on current geophysical dynamics of the ionosphere. Massive the measurements including more than 170 telemetric sessions were analyzed. More than 11000 hours of measurements current of leakage (or runoff current) and measurements of quasi-stationary electric field with discretization 1s and UT binding to each point were analysed. The data measurements, geophysical and orbital data were collected in an electronic album. It is shown that experimental data correlate with the crossing time of the ISS boundaries known geophysical structures: the noon Meridian, the Main ionospheric failure (MIF), the boundaries diffuse intrusion (BDI), the Equatorial Geomagnetic anomaly (EA). In this regard, despite the specificity of the ISS (the spacecraft super big sizes, the most complex spatial configuration) similar measurements, nevertheless, are quite suitable for monitoring researches of some features of an ionosphere at the level of F2 layer with a temporary scale from 1s and can be used for more detailed study of the geophysical structures and related effects in the ionosphere. In addition, the results obtained can be used for the analysis of disturbances of electromagnetic conditions near the surface of the ISS RS, for monitoring potential and currents of leakage on the surface of the ISS.

Procedures are described for the numerical calculation of the electric-field distributions generated in a model ferromagnetic metal slab of thickness d by incident microwave radiation when a static magnetic field is directed along the slab normal and the mean free path ℓ of the charge carriers becomes comparable to, or greater than, the skin depth δ. The model metal is characterized by a local, frequency-dependent permeability; a spherical Fermi surface; and a nonlocal relationship between the current density and the electric-field distribution. The two limiting cases of specular and diffuse scattering of the charge carriers at the slab faces are considered. Electric-field distributions, transmission amplitudes, and surface impedances have been calculated for a wide range of ℓ and d using parameters that simulate nickel. For diffuse surface scattering, the transmission of the magnetically active mode increases at both ferromagnetic resonance (FMR) and cyclotron resonance (CR). A most striking result is the total absence of structure in the magnetic-field dependence of the transmission amplitude near fields corresponding to FMR or to CR for the case of specular scattering. It is demonstrated that very simple formulae provide a good estimate of the free-space transmission amplitudes for both specular and diffuse surface scattering when [Formula: see text] and d/ℓ ≥ 1.

An analytical and numerical modeling of the process of obtaining hydroxyl radicals OH0 and atomic hydrogen H0 from water molecules on a square lattice based on electrical neutralization of ions OH− on an anode and ions H+ on a cathode is conducted. The numerical solution of a system of equations describing a stationary migration of ions H+ and OH− over the interstitial sites of a square lattice located in an external electric field is considered. The ions H+ and OH− in the interstitial sites of a square lattice are generated as a result of dissociation of a water molecule under the action of external electromagnetic radiation and external constant (stationary) electric field. It is assumed that anode and cathode are unlimited ion sinks. The problem is solved using the finite difference approximation for the initial system of differential equations with the construction of an iterative process due to the nonlinearity of the constituent equations. It is shown by using calculation that the dependence of the ion current on a difference of electric potentials between anode and cathode is sublinear.

Quincke Rotation

AbstractImplementation of the well-known phenomenon of Quincke rotation is proposed, which may be called the “photoinduced Quincke rotation (PIQR) effect.” The PIQR effect is based on the previously discovered phenomenon of rotation of a spherical particle in a stationary electric field under continuous irradiation inducing an electric dipole moment in the particle.
