Patent number: 9844101Abstract: A microwave heater comprises a cylindrical housing having an inner surface defining an internal cavity. A microwave generator is secured adjacent a first end of the housing and received inside the internal cavity is a sample holder that comprises an annular base member positioned adjacent the first end has a central axis coinciding with a longitudinal axis of the housing. A first opening is formed along the central axis, an outlet of the microwave generator extending through the first opening along the central axis for emitting into the internal cavity electromagnetic waves centered at a given microwave wavelength. A circular support plate substantially parallel to the base member and concentric therewith, a cavity portion defined therebetween, is separated from the base member by a distance less than the given microwave wavelength for establishing a Transverse Magnetic (TM) 01 mode as a predominant resonance mode inside the cavity portion.Type: GrantFiled: December 22, 2014Date of Patent: December 12, 2017Assignee: SCP SCIENCEInventors: George Feilders, Ali Bostani, Art Ross, Raymond Waterbury, Guobin Ma
