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.
To the choice of collocation points for solving integro-differential equations of electromagnetics
The choice of collocation points for solving integro-differential equations of electromagnetics by the Krylov-Bogolyubov method is considered. Using the example of a simple diffraction problem, variants of the solution for two different systems of collocation points are presented. The first (traditional) system of collocation points is chosen so that the end points do not fall onto the boundaries of the interval. In the second system, the end points fall onto the boundaries. It is shown that both of the systems can be used for solving the problem but the use of the second system provides for a higher accuracy with fewer collocation points.
