Abstract :
Optimized designs for wideband reflector gratings in rectangular waveguide are presented for application in microwave electron beam devices. A moment method procedure for a general dual-plane step in rectangular waveguide and a generalized scattering matrix approach are used to analyze the reflector gratings. A least squares optimization method is used to determine optimized dimensions for reflector gratings which have a constant power reflection coefficient for the TM11 mode over a wide bandwidth
