Abstract: Disclosed is a microwave or radio wave broadcast antenna array constructed to produce rotating fields of energy for broadcast or transmission. The array has an inner conductor enclosed within a tubular outer conductor, and is connected to an energy source. The outer conductor has slots in the wall of the conductor, and rotational polarizers are positioned on either side of the slots to induce rotation and polarization of the transmitted energy.

Abstract: Disclosed is a waveguide for even dispersion of microwaves into a microwave chamber. The microwaves are dispersed in a manner that the target in the microwave chamber does not need to be turned in order to accomplish even and uniform heating of the target. The waveguide includes a first rectangular section adjacent to the source, and a second rectangular section which is sized to separate, disperse and randomized microwaves received from the first waveguide.
