Analytical response sensitivities of infinitesimally thin metallic shapes

Recently, a self-adjoint analytical method was proposed to compute the S-parameter sensitivities of microwave structures from the field solution at the object of interest. However, due to field singularities, the method is inapplicable to infinitesimally thin metallic shapes - a case of interest in the analysis and design of printed circuits and antennas. Here, we propose a formulation, which allows for the analytical calculation of the …
