During this reporting period, we made progress on varactor diode processing approaches appropriate for millimeter and submillimeter wave electronics, on fabricating and measuring diode grids for frequency multiplication and beam control, and especially in the area of grid amplifiers, which promise to deliver higher power at greatly reduced cost for millimeter-wave generation. Millimeter waves, varactor diodes, frequency multipliers, quasi-optical. 收起
