Summary:
We derive analytical shape integral formulas for the shape derivatives of the system matrix arising from the Rao-Wilton-Glisson (RWG) discretized electric field integral equation.Using these formulas and the adjoint variable method (AVM), we inspect sensitivity of input reflection coefficient of a certain UWB dipole antenna with respect to infinitesimal variations of the computational mesh.
The sensitivity obtained with the analytical formula is compared against one calculated with the finite difference approximation.
