Software for unilateral fin-line resonators by full wave analysis

The direct and concise transverse transmission line (TTL) method is used to analyze the unilateral fin-line resonators. This method in conjunction with the Galerkin's procedure and Parseval's relation are applied to obtaining a homogeneous equation system with two variables. The determinant of this system is the complex resonance frequency. The full wave TTL method gives precise and concise equations and the results bring good advantages. Computational programs are developed in Fortran Power Station and MATLAB 5.0, and the results for the unilateral fin line resonator are presented for different parameters including substrate thickness, length and width of the slot resonator, in 2D and 3D.
