Numerical electrodynamic analysis of the external Sestroretskii cube

Аннотация

The paper presents the results of numerical analysis of the frequency characteristics of the external Sestroretskii cube and the comparison of them with the frequency characteristics of the internal cube. It is shown that the external Sestroretskii cube has the properties of a frequency diplexer and a double waveguide triplexer and, at low frequencies, the absolute values of its transmission coefficients tend to those of the internal cube.
