Abstract

This paper presents reduced conditions for the constitutive parameters of lossy bi‐anisotropic media. It is shown that only two separate dyadic conditions, in contrast to the previously reported four, will be necessary and sufficient to characterize a medium as lossy. For the gyrotropic bi‐anisotropic case revisited, it is found that these media call for merely two scalar conditions for their constitutive parameters, in contrast to the nine (reducible to seven) conditions formulated previously. The reduced dyadic and scalar conditions will simplify analysis of the physical realizability and the valid range of parameter values for new composite media. © 2004 Wiley Periodicals, Inc.

## Abstract Conditions for the parameter dyadics are derived for bianisotropic media to be lossy (power absorbing). The conditions, which can be expressed easily in terms of the 6×6 matrix of four parameter dyadics as being Hermitian and negative definite, are brought to the level of individual par

## Abstract The aim of this communication is to correct potential misunderstandings about the PMLs (which are called the MIPMLs) based on __D__–__H__ (__E__–__B__ or __D__–__B__) fields. In fact, the motivation for developing the MIPMLs is to establish accurate and efficient PML absorbers for gener
