ABSTRACT

The H₁₀ mode is scattered from a narrow transverse slot placed over a finite-length dielectric insert completely filling the cross-section of a rectangular waveguide. The magnetic field induced by the slot in the dielectric, directly beneath the slot, is found with the use of the eigenwave technique and the tensorial Green function. Power parameters of the slotted waveguide radiator are determined. Correctness of the mathematical model constructed is confirmed by comparison of the model-based test computations with the results obtained with a commercial simulation code. A possibility has been discovered of ensuring a close to unity radiation efficiency from the slot.
