Abstract:
A novel rigorous solution of the problem of mode diffraction by the junction between a
straight and a uniformly curved rectangular waveguide is presented. The generalized
scattering matrix of the unit is obtained via the matrix operator technique. The fullwave
model is based on Cayley’s transformation between a reflection and an accretive
operator. The convergence of approximate solutions is established analytically. The
computational efficiency of the method is demonstrated. The power conservation law
and the reciprocity relations are used in the operator matrix form. The approach
proposed can be useful for numerical-analytical solution of various electromagnetic
problems
