A simple leaky-wave analysis of 1-D grooved metal structure for enhanced microwave radiation.

We present a simple analytical solution for a one dimensionalgrooved structure which, when placed concentricallyaround or flanking a small aperture, has been shown to enhancemicrowave radiation from it.We will show that the transcendentalequation which describes the grooved structure reduces to a tr...

Description
Summary:We present a simple analytical solution for a one dimensionalgrooved structure which, when placed concentricallyaround or flanking a small aperture, has been shown to enhancemicrowave radiation from it.We will show that the transcendentalequation which describes the grooved structure reduces to a transverseresonance condition at the slot openings. For some parameters,the solution to the problem manifests as a complex wave. Wedemonstrate that this complex wave indeed well approximates thefield distribution when a single aperture is excited for frequencieswhere the enhancement ismost significant. In addition, we proposea simple and intuitive design procedure for the grooved structure
