Combined microwave/frying apparatus

An infrared detector device is described. It is based on an infrared analog of the Fabry Perot interferometer, using one curved, fully reflecting, plate and one planar, mainly reflecting, but partially transmitting, plate. The space between these plates behaves as a resonant cavity which can be built to respond to either a broad or a narrow band of wavelengths in the general range between 1 and 15 microns. It is also possible to combine several detectors of different narrow bands in a single device. Actual detection of the radiation is based on use of thin film resistors, having a high thermal coefficient of resistance, that are thermally isolated from the other parts of the structure. Details relating to the manufacture of the devices are given.

A corrugated waveguide is disclosed comprising a cylindrical body with outer and inner surfaces. The inner surface is provided with plurality of ridges uniformly spaced around the inner surface. Presence of 2n ridges secures the formation of microwaves with stable TE.sub.n1 modes where n is an integer and n&gt;1. Disclosed also is an electron cyclotron resonance system for plasma processing of which system the corrugated waveguide described in the above is a part.

A microwave power combiner is formed in a cylindrical hollow metallic housing utilizing a number of pie shaped chambers formed with metallic vanes attached to and extending radially inward from the interior sidewalls of the cylindrical hollow metallic housing. Individual microwave power sources exterior to the cylindrical hollow metallic housing transmit energy into the pie shaped chambers. Two ring shaped metallic vane straps are used to control impedance mismatches and the resonant frequency of the microwave power combiner. The microwave power from the individual microwave power sources combine in the cylindrical hollow metallic housing and is extracted through the circular top of the cylindrical hollow metallic housing by means of a waveguide or a transmission line. The individual microwave power sources can be replaced as needed without affecting impedance matching or the efficiency of power transfer. There is flexibility in the number of individual microwave power sources used.
