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