Equivalent surface impedance of a slot impedance load on the basis of a cavity with an equilateral triangular cross section

Resumo

The problem of plane-wave excitation of an impedance load on the basis of a slot in an infinite perfectly conducting screen closed from one side by a cavity with an equilateral triangular cross section is considered. The problem is solved by the integral equation method. The numerical solution of the integral equation is performed by the Krylov–Bogolyubov method. For an H-polarized incident wave, the impedance as a function of the slot and cavity sizes and the angle of incidence of a plane wave is calculated.
