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 parameter dyadics as four separate dyadic conditions. The theory is applied to three particular medium classes: bi‐isotropic media, uniaxial bianisotropic media, and gyrotropic bianisotropic media as a set of inequalities for the scalar parameters. The conditions are needed for judging the physical realizability of parameter values of new composite media. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 175–178, 2001.

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
