TM-WAVE RADIATION FROM FINITE THICK SLITS IN PARALLEL-PLATE

The problem of TM-wave scattering and radiation from a finite number o f thick slits in a parallel plate waveguide is solved. The Fourier tra nsform and the mode matching are used to obtain simultaneous equations for the field inside the slits. The simultaneous equations are solved to obtain a series solution which is amenable to numerical computatio n. The numerical computations are performed to illustrate the behavior s of scattering, transmission, and reflection in terms of incident ang le, slit size and operating frequency. The presented solution is compu tationally very efficient and useful for slotted-waveguide leaky-wave antenna applications.
