Electromagnetic Wave Propagation in a Moving Chiral Medium
نویسنده
چکیده
We analyze the propagation of an electromagnetic plane wave through a chiral medium moving with a constant velocity and endowed with the Post constitutive relations. The covariance under the Lorentz group of Maxwell’s equations and of Post’s relations is used to transform the electromagnetic fields in the moving frame into fields in the frame of a fixed observer. The physical consequences of the motion on the physical properties of the electromagnetic fields are discussed.

Plane Wave Reflection and Transmission from Uni- and Bi-Axial Chiral Slabs
In this paper, the propagation of electromagnetic waves through an infinite slab of uni- or bi- axial chiral medium is analytically formulated for an arbitrary incidence using 4×4 matrix method. In this powerful method, a state vector differential equation is extracted whose solution is given in terms of a transition matrix relating the tangential components of electric and magnetic fields at t...
متن کاملElectromagnetic wave propagation through a dielectric-chiral interface and through a chiral slab
The reflection from and transmission through a semi-infinite chiral medium are analyzed by obtaining the Fresnel equations in terms of paralleland perpendicular-polarized modes, and a comparison is made with results reported previously. The chiral medium is described electromagnetically by the constitutive relations D = EE + i-yB and H = i-yE + (1/,)B. The constants , u, and -y are real and hav...
متن کاملNegative– and positive–phase–velocity propagation in an isotropic chiral medium moving at constant velocity
Analysis of electromagnetic planewave propagation in a medium which is a spatiotemporally homogeneous, temporally nonlocal, isotropic, chiral medium in a co–moving frame of reference shows that the medium is both spatially and temporally nonlocal with respect to all non–co–moving inertial frames of reference. Using the Lorentz transformations of electric and magnetic fields, we show that plane ...
متن کاملWave Propagation in Nanocomposite Materials
Electromagnetic wave propagation is first analyzed in a composite material mde of chiral nano-inclusions embedded in a dielectric, with the help of Maxwell-Garnett formula for permittivity and permeability and its reciprocal for chirality. Then, this composite material appears as an homo-geneous isotropic chiral medium which may be described by the Post constitutive relations. We analyze the pr...
متن کاملAn Idea for Electromagnetic "Feedforward-Feedbackward" Media
In this paper, an idea for a new class of complex media that we name feedforward–feedbackward (FFFB) media is presented and some of the results of our theoretical work in analyzing plane wave propagation in the axial direction through these media are described. The concept of FFFB media, as introduced here, was inspired by the theoretical research of Saadoun and Engheta on a variation of artifi...
