Abstract :
An overview of the theory, properties, and potential applications of compound slots is given. Methods for analyzing compound slots are discussed. Scattering properties of the compound slot are examined, covering resonance and the equivalent circuit model, resonant length scattering in the main waveguide, the aperture electric field, and off-resonant characteristics. Array characteristics are also considered, including external mutual coupling, internal higher order mode coupling, and some factors to consider in designing array configurations. Problems remaining to be solved are indicated.<>
