Implementation of time-domain wave-splitting method to the scattering problems in stratified chiral medium
TLDR
In this paper, the wave splitting method is used to analyze a plane wave incident into an infinite inhomogeneous lossless chiral medium, where the permeability, the permittivity and the chiral admittance varies with the depth.Abstract:
This paper introduces the wave-splitting method and it is important that the Green's functions derived by this method are independent of the incident and scattered fields and depend only on the properties of the medium, so we use the functions to analyze a plane wave incident into an infinite inhomogeneous lossless chiral medium, where the permeability, the permittivity and the chiral admittance varies with the depth.read more

Bi-isotropic constitutive relations
Ari Sihvola,Ismo V. Lindell +1 more
TL;DR: In this paper, the constitutive relations of general bi-isotropic media, requiring four material parameters, can be written in different ways to describe their electromagnetic behavior, and a two-way "dictionary" is presented between a proposed formulation of the relations with three other sets of relations, generalized from relations used for chiral materials.
Transient wave propagation in reciprocal bi-isotropic media at oblique incidence
Gerhard Kristensson,Sten Rikte +1 more
TL;DR: In this article, a new wave splitting method was proposed that simplifies the analysis of wave propagation in reciprocal bi-isotropic media, and two different methods to solve the scattering problem were analyzed; the invariant imbedding and the Green function approach.

On electromagnetic waves in chiral media
TL;DR: In this paper, the propagation of electromagnetic waves through chiral media is analyzed, i.e., through composite media consisting of macroscopic chiral objects randomly embedded in a dielectric, and the peculiar effects that such media have on the polarization properties of the waves are placed in evidence.

Electromagnetic wave propagation through a dielectric–chiral interface and through a chiral slab
TL;DR: In this paper, the reflection from and transmission through a semi-infinite chiral medium is analyzed by obtaining the Fresnel equations in terms of parallel-and perpendicular-polarized modes, and a comparison is made with results reported previously.

Direct and inverse scattering in the time domain for a dissipative wave equation. Part 1: Scattering operators
TL;DR: In this article, a series of papers devoted to direct and inverse scattering of transient waves in lossy inhomogeneous media is presented, where the medium is assumed to be stratified, and the wave propagation is modeled in an electromagnetic case with spatially varying permittivity and conductivity.

Direct and inverse scattering in the time domain via invariant imbedding equations
TL;DR: In this article, a new approach to direct and inverse scattering problems in the time domain is proposed, which is applied here to the case of a one-dimensional lossless medium, based on an integro-differential equation which is satisfied by the reflection kernel.
