Abstract :
Using a published formulation of the equations for the reflection of an electromagnetic wave from a transversely magnetized ferrite block in a rectangular waveguide, a solution in closed form for the integral equation involved is given. A detailed discussion of this solution in a certain range of the gyromagnetic parameter follows. Outside this range the published solutions are shown to be faulty, and the present solution is also unusable, for unknown reasons. A second-order solution is also given, and reasons are advanced for believing that quasi-static approximations are not the cause of the difficulties encountered.
