Optimisation de forme d'antennes lentilles intégrées aux ondes millimétriques

Abstract : Integrated lens antennas are devices having electromagnetic waves as support and are composed of a primary source and a dielectric focusing system. The recent increase of applications in millimetric waves (example :adaptative cruise control radars), needs the design of lens antennas of a fex centimeters with specific requirements. One of the problems consists in determining the optimal shape of the lens given : (i) the primary source, (ii) the radiation pattern. This PhD thesis project aims to develop new tools for shape optimization using integral formulation of the problem.
This PhD thesis is structured in two parts. In the first one wa have constructed sevral integral formulations for the dielectric scattering problem using boundary integral equation approach. In the second one we have studied the shape derivatives of the standard boundary integral operators in electromagnetism in order to incorporate this derivatives in shape optimization algorithms
