T-shaped branching rectangular waveguides with a ferrite parallelepiped

The paper presents the results of the research of the H/sub p0/ wave scattering on a T-shaped branching of rectangular waveguides with a transversely magnetized ferrite parallelepiped (FP). The analysis is based on the rigorous solution of the diffraction problem, obtained by the partial regions method with singling out the coupling region through conditions of biorthogonality of eigen functions for transmission lines with gyrotropic filling. The approximate solution in the analytical form is obtained and its accuracy is established.
