Analysis of the infinite array of slot impedance loads based on the cavity with an equilateral triangular cross section
Two-dimensional problem of an infinite array of slot impedance loads by the plane wave is considered. Each array element represents a slot in a perfectly conducting screen loaded by a cavity with equilateral triangle cross-section. The integral equations method is used to solve the problem, the Krylov-Bogoliubov method is applied to calculate them. For the case of H-polarized incident wave equivalent surface impedance dependencies on construction geometric sizes is calculated. Comparative analysis of dependencies obtained for construction under consideration of an infinite array of slot impedance loads with those ones for single impedance load is carried on.
The equivalent surface impedance of a slot impedance load implemented as a slot in a screen (the E polarization)
In the case of the E polarization, the equivalent surface impedance of a slot impedance load which is implemented as a slot in a screen is determined using simulations. The problem is reduced to a rigorous integro-differential equation solved by the Krylov-Bogolyubov method. The equivalent surface impedance is calculated as a function of the slot dimensions at various medium parameters and plane wave incidence angles.
