Fast analysis of gap waveguides using the characteristic basis function method and the parallel-plate Green’s function

Paper i proceeding, 2012

The Characteristic Basis Function Method is employed in conjunction with the parallel-plate dyadic Green's function method to obtain the impedance characteristics of electrically large gap-waveguide structures. Numerical results are shown for the groove gap waveguide demonstrating reduced execution times relative to the HFSS software, while the solution accuracy is barely compromised.
