New method for exact self-adjoint sensitivity analysis of metallic shapes

Summary form only given, as follows. A new sensitivity analysis method is proposed to compute the S-parameter Jacobian for metallic shapes. The method is exact in the sense that it uses an analytical formulation, which is independent of the method of numerical full-wave analysis and the respective system matrix. It uses only the field solution on the surface of the metallic objects. The field solution can be provided by any valid electromagnetic analysis.
