Abstract
Transverse magnetic (TM) plane-wave scattering from a rectangular channel engraved in a perfectly conducting plane is investigated. A Fourier-transform technique is employed to express the scattered field in the spectral domain in terms of parallel-plate waveguide modes. An approximate series solution for scattering is presented in a closed-form which is valid for the high-frequency scattering regime. Approximate solutions which are valid for the quasi-static and low-frequency scattering regimes are also obtained. Using the stationary phase approximation, the far-zone scattered field is obtained and its scattering behavior is studied in terms of the scattering angle, frequency, and channel size.<>
