The nonlinearity of magnetic induction dependence upon magnetic-field strength is considered. The developed model is the generalization of well-known ones for nonferromagnetic solids. Interconnection of electromagnetic, temperature and mechanical fields is taken into account by Joule's and hysteresis heat and ponderomotive forces averaged on the period of an electromagnetic wave. In such an approach, the calculation procedure reduces to consecutive resolving of electrodynamics equations for ferromagnetic media (first stage) and uncoupled quasistatic thermoelasticity problems at given boundary and initial conditions (second stage).","PeriodicalId":270641,"journal":{"name":"MMET '96.

For wide band matching of the H-plane tee with a conductive lug, it has been proposed to bring the additional matching elements based on a frequency-selective structure, formed by rectangular (also rectangular with rounded inner angles) ledges made in the side walls of side waveguide. A tee with two compensative ledges has been considered. Such design distinguishes with unit simplicity that simplifies its production in the millimeter range. Moreover, such a way of matching improves the electric strength that makes it possible to be used in devices operating at increased power levels.","PeriodicalId":270641,"journal":{"name":"MMET '96.
