Abstract : Some fundamental concepts of Orthotr n operationARE PRESENTED. By utilizing general power and energy relations, the performance of an Orthotron is related to a magnetron oscillator with the same cross section. The first case studied was an axially-uniform structure, and the rate of growth of Orthotron power is shown to be inversely proportional to the product of the group velocity of the Orthotron structure and the Q (minimum) of the magnetron. In the second case, the structure consists of axially-short sections coupled together to form a periodic network. The operation in this case is basically the same as in the first except that the gain (per unit length) - bandwidth product may be increased by decreasing the length of the individual sections. The reverse component of power is assumed to be negligible in the first two cases. The problem including the reverse power is formulated, and the mechanism of reverse power cancellation is considered for two special cases. (Author)
