Design Optimization of H-Plane Waveguide Component by Level Set Method

We present a design optimization method of H-plane waveguide components, based on the level set method with the finite element method. In this paper, we propose a new formulation for the improvement of a level set function, which describes shape, location, and connectivity of dielectric in a design region. Employing the optimization procedure, we demonstrate that optimized structures of an H-plane waveguide filter and T-junction are obtained from an initial structure composed of several circular blocks of dielectric. key words: design optimization, level set method, adjoint variable method, finite element method, H-plane waveguide component
