Abstract :
The low-impedance transit-time oscillator (LITTO) without foils is a new high-power microwave generator. Its main operation mode is the coaxial transverse mode TM01 . This paper solves the field distributions and the corresponding beam coupling coefficients in the LITTO. As shown in this paper, the modulating electric field in the multicavity LITTO can be derived from a single-cavity theory; thus, its corresponding beam coupling coefficient can be easily obtained.
