Abstract :
Based on the adjoint network method (ANM) and on mode matching technique, an extremely efficient optimization tool 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.<>
