Abstract :
Small-signal negative conductance of a field emission monotron was calculated, which was considerably higher than that of a thermionic monotron due to strong bunching of emitted electrons in field emission. An amplification constant of 1.4 dB/mm is achieved in the THz wave region by applying the monotron to a distributed amplifier. A wide band tunable electromagnetic wave may be generated in the THz wave region by providing a low loss microstrip line resonator with an FEA due to the gate voltage dependent phase constant of the line.
