Abstract
In article models of the microwave oven of heating of objects are considered. One of them represents the generator of the microwave oven of the energy, loaded on the volume resonator in which place heated up object. Other model, along with the microwave oven the generator, contains the switching center with exits on a number of unidirectional radiators in which aperture the irradiated object is established. In article it is considered features of process of interaction of object with a wave guide field. Modes of the minimum rcradiation of energy and the maximum absorption of energy are in detail stated.
