A transmission-line matrix model suitable to model the propagation of electromagnetic (EM) waves in hi-isotropic media is presented. The main characteristic of the EM response of such complex media is the cross coupling of the EM field vectors in their constitutive relations. In this study, the angle tilt between electric and magnetic field vectors, the intrinsic impedances, the effective parameters of the medium, and the rotation of the polarization plane are computed. The results are in very good agreement with the theoretical solution. [ABSTRACT FROM AUTHOR]

In this paper, the characteristics of layered structures (photonic or electromagnetic bandgaps), including chiral media, are studied by means of two different numerical methods, one in the time domain (finite differences in the time domain, FDTD) and the other in the frequency domain (coupled-mode method, CMM). The results (reflection and transmission coefficients for a plane wave normally incident over a layered structure) obtained by means of both well different techniques are practically identical.

The coupled mode method (CMM) is a seminumerical method for studying electromagnetic propagation, originally formulated for closed structures. We show how this method can be used for obtaining the propagation constants and electromagnetic field in unbounded isotropic chiral media. We also characterize single and periodic cascade discontinuities made of isotropic chiral slabs by means of the mode matching method combined with the CMM. The results are tested with a robust FDTD technique, modified to model bi-isotropic media and with analytical solutions. In all cases good agreement is found. © 2007 Wiley Periodicals, Inc.

A time-domain solution of electromagnetic wave propagation in Tellegen materials is presented. The angle tilt between electric and magnetic fields, the phase speed of the wave, and the intrinsic impedance are computed when the medium is excited with a monochromatic source. The results are in good agreement with theoretical predictions. © 2003 Wiley Periodicals, Inc.
