Topics in Guided Wave Propagation Through Gyromagnetic Media

Abstract

Some problems, complete discussion of which would be extremely difficult, are treated approximately by means of perturbation theory. Among these are the partially filled cylindrical waveguide, and the problem of multiple internal reflections in a sample of finite length filling the cross section of a cylindrical guide. Propagation in a ferrite between parallel planes, magnetized along the propagation direction is discussed by the methods described in Part I. The paper concludes with an addendum to Part I — a numerical study of field patterns of the TE <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> -limit and TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> -limit mode for various dc magnetic fields.
