Propagation of electromagnetic waves in a medium with nonlinear magnetic susceptibility

The interaction of electromagnetic waves in a medium with nonlinear magnetic susceptibility is investigated. On the basis of Tinkham's measurements an antiferromagnet showing a resonance in the submillimeter region is considered as a nonlinear medium. The solution of both the Landau-Lifshitz and Maxwell equations leads to the RHS wave equation. Its solution with boundary conditions shows that the amplitude of the reflected wave from the nonlinear medium on a combined frequency can be non-zero.     

Propagation of electromagnetic waves in conducting graphene-like carbon nanoallotropes

Propagation of electromagnetic waves in graphene-like conducting carbon crystals with the (C)_4ν and (C)_6ν symmetries is studied. It is demonstrated that only TM waves can exist in such crystals. The comparative analysis of such waves in different structures is performed. It is shown that the structures under study are superior to classical graphene with respect to excitation of electromagnetic waves.     

Propagation of electromagnetic waves in a random medium and nonzero rest mass of the photon

The propagation of electromagnetic waves is studied in a Maxwell vacuum with 0. The photon loses energy during its propagation through this vacuum. This dissipation of energy is related to the fluctuation of the refractive index of the underlying vacuum. There exists a bounded and unique solution in the limit 0 in the asymptotic region. The geometric structure of the background space-time is Finslerian in nature.

Propagation of elastic waves in a nonideal layered medium

The peculiarities of propagation of acoustic excitations through an imperfect 1D superlattice are studied in the virtual crystal approximation. The dependence of the lowest acoustic band gap of a nonideal (disordered in composition) two-sublattice 1D phonon crystal on the concentration of impurity layers is simulated numerically.     

Dispersion process of electromagnetic waves in a moving medium

The propagation of electromagnetic waves in a moving isotropic plasma and in a moving magnetoactive plasma is considered using the invariant methods of tensor analysis. Expressions are obtained for the dielectric permittivity tensor, the dispersion equations, and the refractive indexes of electromagnetic waves in these media. Using these results it is possible to establish corrections to the angular displacement which occurs when radiation passes through a moving electron plasma.Published from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 39, No. 1, pp. 121–129, January, 1996.     

Propagation of electromagnetic waves over a foamed sea surface

We study the propagation of electromagnetic waves over a smooth sea surface with impedance fluctuations due to copious foaming. This problem is solved analytically with allowance for multiple scattering at small grazing angles. An analytical expression for the effective impedance of the mean field is found in the case of large variance in the perturbation of the dielectric properties of the interface.

Propagation of electromagnetic waves in hot magnetoactive plasma

The paper derives the general form of the tensor of dielectric permittivity? _ij(ω,k), Eq. (15), of non-relativistic hot magnetoactive collisionless plasma taking into consideration the influence of spatial dispersion. The general form of the tensor? _ij(ω,k) is used to express the tensorε _ij(ω,k) in the region of weak and strong spatial dispersion and in some special cases. A general dispersion equation (30) is derived and an analysis is made of the waves propagating in hot magnetoactive plasma. The expressions derived are used to investigate the damping of a right-handed circularly polarized wave propagating in hot magnetoactive plasma in the direction of the magnetic field.
