Radiation from an infinite aperiodic array of parallel-plate waveguides

The problem of radiation from an infinite array of parallel-plate waveguides with an arbitrary number of the guides being shorted is considered. By Wiener-Hopf techniques, the reflected field in the waveguides and the radiated far field in the empty half-space are obtained. The results are then applied to evaluate the "edge effect" of a finite array through numerical examples.
