One-Shot Excitation of an Electromagnetic Field in Rectangular Resonator with a Dielectric Plate Located in the H-Plane

An approach for an analytical solution of the inhomogeneous electrodynamics problem for a rectangular resonator with a dielectric plate located in the H plane. The use of the basic principles in electrodynamics - the polarization duality, superposition and orthogonality made it possible to represent the solution of the inhomogeneous Helmholtz wave equations in the form of a superposition of the proper orthogonal E and H-modes without the appearance of hybrid modes. The process of excitation of the electromagnetic field in the resonator by means of a single rectangular slit located in the E and H plane on the upper, lateral and back walls of the resonator is analyzed, which is of interest to improving the excitation systems of the EM field in microwave ovens.
