IMPEDANCE AND PROPAGATION CHARACTERISTICS OF A FOUR COUPLED-LADDER BACKWARD-WAVE OSCILLATOR WITH NONZERO PITCH

Abstract

A general discussion of the theory of backwardwave oscillators is presented and the propagation and impedance characteristics are determined for a backward-wave oscillator having a circuit consisting of four coupled ladders placed across the narrow dimension of a waveguide. Propagation curves and impedance curves are presented for both the fundamental forward and the backwardwave components for several values of pitch and ladder plane spacing. A larger pitch or ladder plane spacing increases the frequency corresponding to a given phase constant. The results indicate that the coupled-ladder backward-wave oscillator can be an effective source of microwave power.
