Transversal Slot in a Waveguide with Dielectric Slow-Wave Structure

N. K. Blinova, A. A. Lyakhovsky, L. P. Yatsuk


The physical properties of a narrow transversal slot cut in a rectangular waveguide with a dielectric layer parallel to the waveguide broad walls are studied on the base of calculations. The possibility for slot resonance radiation in a single-mode operation is shown for the condition that the waveguide wavelength is shorter than that for the free space. The recommendations for the task-oriented choice of slot length, layer permittivity, its thickness and position in a waveguide section are given. The reliability of the results calculated is confirmed experimentally.
