Refractive Medium

According to Maxwell equations and constitutive relations in chiral medium, the dispersion characteristic of the symmetric slab waveguide with chiral negative refractive medium is studied. The dispersion equations expressed in the normalized parameter are deduced in the slab waveguide. The numerical results show that the chiral parameter has great influence on the dispersion characteristic of slab waveguide. When the relative chiral parameter is about 0.0477, the zero order mode of left-handed polarized wave disappears. While it is greater than 1, the core becomes chiral negative refractive medium and the zero order mode disappears. In addition, compared with the general chiral waveguide, the tendency of dispersion curves in slab waveguide with chiral negative refractive medium is also analyzed.

The dispersion characteristics of surface TM modes in a hollow slab waveguide which consists of the core and substrate of right-handed material (RHM) and the cover of left-handed material (LHM) are investigated. Normalized frequency, normalized propagation constant and asymmetry measure are introduced to the left-handed material hollow slab waveguide. The dispersion relation is derived by using these normalized parameters, and universal dispersion curves are obtained by solving transcendental dispersion equations analytically. Existence condition and other dispersion characteristics of guided surface TM modes have been discussed in detail for different permittivity of three layers for this left-handed material hollow dielectric slab waveguide.

Magnetostatic Surface Wave

Nonlinear magnetostatic surface wave in a slab waveguide structure has been investigated. The design consisted of dielectric film between two thick nonlinear nonmagnetic negative permittivity material (NPM) layers. A dispersion relation for TE nonlinear Magnetostatic surface waves (NMSSWs) has been derived into the proposed structure and has been numerically investigated. Effective refractive index decreases with thickness and frequency increase have been found. Effective refractive index decrease with optical nonlinearity increase and switching to negative values of effective refractive index at a certain value of optical nonlinearity have been found. This meant that the structure behaved like a left-handed material over certain range. We found that the power flow was changing by changing the operating frequency, the dielectric film thickness, and the optical nonlinearity. Also, the effective refractive index and power flow attained constant values over certain values of dielectric constant values.
