Abstract
The two-dimensional problem about the excitation of an infinite array of slot impedance loads by a plane wave is considered. The aim is the determination of the equivalent surface impedance. Every array element is a slot in a perfectly conducting screen. The slot is loaded by a cavity having the cross-section in the form of an equilateral triangle. The problem is solved using the integral equation method, which is numerically realized with the use of the Krylov—Bogolyubov method. The dependences of the impedance on the slot dimensions, the cavity dimensions, and the plane wave incidence angle are calculated for the case of the H polarization of the incident wave. The dependences obtained for the considered construction of the impedance load contained in an infinite array are analyzed and simultaneously compared with the characteristics of a single impedance load.
