MILLIMETER GENERATION AND NONLINEAR PROPAGATION IN FERROMAGNETICS REPORT NUMBER 4 (1 July – 30 September 1963)

摘要

1. The computer investigation of transient spin wave build-up has been extended to further parameter ranges, and generalized to include spin waves from the complete spin wave manifold. The result defines the parameters required in the high power type II device to avoid spin wave degradation, and predicts a favorable result for high power generation.n2. Work on production of pulsed magnetic fields to meet the new requirements for high power type II generators has encountered several new, and initially disturbing, effects, mostly concerned with scaling of the pulsing lines to lower impedance levels. All but one of these effects has been overcome, and the last is being studied.
