Surfacewave diffraction at the open end of a circular semiinfinite dielectric waveguide
Abstract
The method of integral equations is used to study surfacewave diffraction at the open end of a circular dielectric waveguide. A region of limited size near the irregularity is isolated in the waveguide. The electromagneticfield distribution on this region has a complex structure, while outside this region the field distribution has the form of a superposition of a finite number of propagating natural modes with unknown amplitude factors. This approach makes it possible to obtain a numerical solution to the set of integral equations with respect to the unknown densities of the electric and magnetic equivalent surface currents. Calculation results are presented for two values of the radius of the circular dielectric waveguide.
