Effect of anisotropic magneto-chirality on the characteristics of a microstrip resonator

The effect of a chiral bi-anisotropic substrate on the complex resonant frequency of a rectangular microstrip resonator has been studied on the basis of the integral equation formulation. The analysis is based on the numerical solution of the integral equation by using the Galerkin procedure for the moment method in the spectral domain. This work aims to study first the effect of the chirality of a bi-anisotropic substrate upon the resonant frequency and the half-power bandwidth, and then the effect of magnetic anisotropy via an asymptotic approach for very weak substrate upon the resonant frequency and the half-power bandwidth. The computed results are found to be in good agreement with the previously published work.
