Energy Concentration Effects in Ferrite Loaded Wave Guides

Abstract

The primary objective of this study was to determine the effects of geometric parameters on microwave transmission characteristics for two counter-rotating circularly polarized waves in ferrite loaded wave guide. Ferrite rods were mounted coaxially in circular wave guide of 0.934 in. diameter. Effects of rod diameter and length were observed on reflection, phase shift or Faraday rotation, and ellipticity. Effects of frequency and applied magnetic field were observed in addition to differences in energy concentration in a ferrite for the two circular waves. A greater percentage of the microwave energy is found to be in the ferrite for one rotating component than for the other. It is shown that Faraday rotation of large diameter rods cannot be used to characterize ferrites accurately.
