Abstract

ABSTRACT In this study, the Transmission-Line Modeling (TLM) method is extended and applied to the time-domain simulation of electromagnetic wave propagation in materials displaying magnetoelectric coupling. The formulation is derived from Maxwell's equations and the constitutive relations using bilinear Z-transform methods leading to a general Padé system. This approach is applicable to all frequency-dependent linear materials including anisotropic and bianisotropic media. The close agreements between the results obtained from the time-domain simulations and analyses for examples involving isotropic and uniaxial chiral materials indicates that the numerical approach can be applied with confidence to problems having no analytic solution.
