Abstract:In this thesis, we have developed a finite-difference-based frequency domain scheme to analyze a wide variety of waveguides and microstrip lines. The formulation is generalized to account for anisotropic, lossy substrates. In order to speed up the algorithm, the discretization is limited to the two-dimensional transverse plane while propagating the wave analytically along the longitudinal direction. The performance of the algorithm is further improved by using Krylov subspace-based reduction techniques to solve the sparse matrix equation. The numerical technique is also extended to analyze single and multiple discontinuities in the waveguiding structure. Finally, some preliminary work is done on truncation of the computational domain using perfectly matched layers (PML) as a material absorbing boundary conditions.
