Parasite-free non-orthogonal finite-difference frequency-domain method for the analysis of inhomogeneous lossy waveguides

Research output: Contribution to conferencePaperpeer-review

Abstract

A non-orthogonal finite-difference approximation of Maxwell's curl equations in the frequency domain is proposed for the dispersive analysis of inhomogeneous, lossy, waveguiding structures. The occurrence of spurious modes is avoided by the direct enforcement of Gauss's law in the development of the matrix eigenvalue problem. Perfectly matched layers, constructed using coordinate stretching are used to effect grid truncation for the case of unshielded waveguides. Calculated ω - β diagrams for both shielded and unshielded waveguides are in excellent agreement with published results obtained using analytic or finite element techniques.
