3D inverse scattering by level set with zero capacity connecting set. Wave guide optimization by "zone"

The interest of this paper is to present a new technique of shape optimization for the metallic structures of waves guide type. This method ensues from the technique of level set 3d type [DUBOIS 2006], [DUBOIS 2 2006], [LITMAN 2000] and [FERRAYE 2002]). This last one, the calculus of the associated shape gradient by the min max theory ([ZOLESIO 2004] and [MOUBACHIR 2006]), as well as the numerical results on the structures rebuildings with toplogic changes, were presented notably at the last edition of the JINA 2004.
