Numerical modules for gradient computations in electromagnetics

Participants : Claude Dedeban [ France Télécom, La Turbie ] , Pierre Dubois [ former PhD ] , Jerôme Picard [ former engineer ] , Jean-Paul Zolésio.

Shape gradients with respect to 3D geometries in electromagnetic fields are computed by numerical code developments peripherical to the France Télécom SR3D code for the solution of the Maxwell equations. These developments, combined with interpolation in the frequency domain, permit to compute the derivative w.r.t. the frequency.

Additionally, a self-sufficient FORTRAN code is being developed for antenna optimization by parameterized level-set techniques. This code is to be latter interfaced with the code for array antenna optimization.
