An efficient integral equation technique for the analysis of arbitrarily shaped capacitive waveguide circuits

In this contribution a new and efficient integral equation formulation is presented for the analysis of arbitrarily shaped capacitive waveguide devices. The technique benefits from the symmetry of the structure in order to reduce the dimensions of the problem from three to two dimensions. For the fi...
