ABSTRACT:
A microwave oven with an oven cavity and a microwave feed system which produces a microwave distribution of polarized microwaves with essentially defined field vector orientations relative to one of the walls of the cavity. A zone defining an expansion of volume which opens into the cavity and whose dimensions are tuned to the wavelength and field distribution in the cavity, is disposed in a wall of the cavity. The expansion does not affect the effective field distribution in the cavity and can be used for concealed placement of a grill element or light source.
