High-power even- and odd mode emission from linear arrays of resonant-tunneling-diode (RTD) oscillators in the 0.4- to 0.8-THz frequency range
Fanqi Meng, Zhenling Tang, Petr Ourednik +4
Resonant tunneling diode (RTD) oscillators possess the highest oscillation frequency among all electronic THz emitters. However, the emitted power from RTDs remains limited. Here,…
