A small-signal theory is developed which simultaneously includes the diocotron, negative mass, and cyclotron maser effects. The simple analysis is performed using a Pierce type approach for an axis encircling electron beam inside a circular waveguide. Relativistic, nonrelativistic, synchronous, and nonsynchronous limits are considered to recover the… (More)
