Abstract
An analysis of the behavior of thin magnetic films of Permalloy when used as time variable inductors has been made in terms of a modified Landau-Lifshitz equation. These results show that parametrons using time variable magnetic film inductors can be made to operate at reasonable power levels with large grains per cycle at oscillating frequencies in the 100- to 500-Mc region. A way of fabricating magnetic film parametrons with strip line techniques is shown. Calculations indicate that units with dissipations in the 10 mw range are feasible with existing techniques for operation in the 100- to 500-Mc region. Ways of advantageously using capacitive coupling between parametron units is indicated in which the two new subharmonic states of a magnetic film parametron created by a bias reversel are used.
