Impulse signal propagation in open dielectric circular waveguide

Abstract

The paper considers generalization of Mode Basis Method for calculation of pulse signal propagation in a circular open dielectric waveguide. The mode functions are calculated by Integral Equations Method. It is shown that the circular dielectric waveguide possesses only continuous spectrum. Then an integral-differential System of Evolutionary Equations is obtained that describes mode amplitudes evolution in time with propagation. Its solution by the method of moments is proposed. Propagation of some pulse signal in a circular dielectric waveguide is calculated.
