In the resonator, large numbers of devices (HEMT, HBT, etc. ) are arrayed two dimensionally and mounted on a surface of a metal grooved-mirror. A newly developed equivalent circuit for the resonator has been constructed using a transmission-line model. Experiments performed at Ku-band have shown that oscillation frequencies in a 33 HEMT array oscillator can be predicted with errors of less than 1% by using this equivalent circuit., application/pdf}, pages = {856--861}, title = {Design of a Quasi-Optical Oscillator Using a Grooved Mirror with a HEMT Array}, volume = {E81-C}, year = {1998} }
