Millimeter and submillimeter-wave quasi-optical oscillator with multi-elements

Multielement oscillators with a quasi-optical resonator are reported. The resonator consists of a Fabry-Perot cavity with a grooved mirror (grating) and a concave mirror. It is possible to mount solid-state devices (Gunn diode, GaAs MESFET, etc.) in the grooved mirror. The oscillator has the capability for power-combining of solid-state sources in the millimeter- and submillimeter-wave regions.<
