Abstract :
An extremely efficient optimization tool, where the fullwave mode matching simulator is driven by a quasi-Newton optimizer using the adjoint network method, has been developed for the CAD of a class of rectangular waveguide components. This includes filters, phase shifters, branch guide couplers, etc., with step in either the E- or H-plane. With respect to the conventional finite difference computation of the derivatives, a speedup factor of more than 10 times is easily achieved
