The Vane-Loaded Ladder Slow-Wave Circuit
Abstract
This paper investigates the vane loaded ladder slow wave circuit. This circuit, derived from the interdigital line, is examined as a possible alternative to circuits currently used in crossed field amplifiers (CFA's). Its configuration is designed to possess wideband dispersion and to allow access to the fundamental forward-wave space harmonic through altered electric field distributions. The analytical results show that the circuit possesses intrinsic shortcomings which prevent full realization of the desired features. While it does preserve the wideband dispersion of the interdigital line, it also introduces some undesirable characteristics. Furthermore, the new electric field distributions contribute to the desired impedance behavior only under limited circumstances. In general, the impedance characteristics which inhibit the interdigital line as a forward-wave circuit are present in the new circuit to the same degree. It is concluded that typical CFA circuits, such as the stub-support meander line, are more advantageous. Ladder circuit, Vane loaded, Slow wave, Crossed field amplifiers, Traveling wave tubes.
