Abstract

The behavior of the electromagnetic fields is studied at the common edge of a number of wedges consisting of lossless biisotropic, perfect electric conducting, and/or perfect magnetic conducting materials. A general matrix formalism is constructed to find the transcendental equation for the singularity exponent. This singularity exponent equation is examined in detail for two important cases: 1) two bi-isotropic wedges with common edge, and 2) two bi-isotropic wedges and a perfect electric conducting wedge. A generalization of the theory to a special class of bi-anisotropic wedges is also presented
