The problem of TM-mode scattering from the finite number of rectangula
r notches in a parallel plate waveguide is considered. The Fourier-tra
nsform is employed to obtain simultaneous equations and the simultaneo
us equations are solved to obtain an analytic solution in rapidly-conv
ergent series. Numerical computations are performed to investigate the
scattering behavior in terms of frequency and notch sizes. The presen
ted theory is applicable to the analysis of scattering from the E-plan
e stubs in the rectangular waveguide.
