Analysis of unilateral fin-line resonators on biaxial substrates via spectral domain technique

The admittance Green's function is derived through a fourth order formulation. A verification of the theoretical results is presented. This technique can be extended to include the magnetic substrate problems where the permeability is a second rank tensor. Even though this analysis is directed toward a single uniform slot, arbitrarily shaped resonators can also be analyzed using this method, as long as the correct field expansion functions are provided. >
