MICROWAVE APPLICATOR, SYSTEM, AND METHOD FOR PROVIDING GENERALLY CIRCULAR HEATING

摘要

A microwave applicator assembly includes a microwave applicator that excites TE modes and provides a generally circular heating pattern in a lossy dielectric material. The microwave applicator has a processing chamber bounded by a circumferential wall in which a plurality of indents are formed. The microwave applicator assembly may further include a feed waveguide coupled to the microwave applicator for inputting microwaves into the processing chamber. The microwave applicator assembly may further include one or more choking sections in communication with the processing chamber to enhance heating efficiency and reduce microwave leakage.
