Numerical techniques to compute the cutoff frequencies, modal fields, and dispersion characteristics in microwave planar media

Numerical techniques for calculating modal fields, cutoff frequencies, and dispersion characteristics in shielded microwave planar transmission media are developed. The formulation uses the method of images to derive a Fourier series expression for the current on the inner conductor, a one-dimensional Green's function (which was derived by transforming Maxwell's equations into the spectral domain) to evaluate the electric field, and point matching in the moment method to find the source-free solution. To decrease computation time and to improve the representation of the slowly-converging electric fields, an acceleration technique is used.
