Аннотация:An asymptotic representation of the electromagnetic field in the vicinity of an edge in a waveguide filled with a transversely inhomogeneous dielectric is obtained. The case of a reentering edge is analyzed in detail. A method for investigations of waveguide problems is proposed which enables one to represent the field in the neighborhood of the boundary irregularity accurately to terms of an arbitrary order of smoothness.
