Abstract
The characteristics of the waveguide modes in premagnetized ferrites are described, taking into account the dielectric and magnetic losses. It is shown that the field distributions inside an anisotropic medium-filled rectangular waveguide can be calculated on the basis of a rigorous field theory. The authors then discuss how the field theory can be used for the design of high-quality isolators and phase shifters.<>
