Propagation of electromagnetic waves in a rectangular waveguide with periodic lattices

The problem of propagation of electromagnetic waves in a waveguide with one or two periodic lattices of simple or special form is solved in strict formulation. The formulas obtained are studied by computer, and the numerical results obtained analyzed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 21, No. 12, pp. 1834–1839, December, 1978.The author considers it her pleasant duty to thank V.
