Pulse Signals in Open Circular Dielectric Waveguide

By Maxim N. Legenkiy and Alexander Butrym
Progress In Electromagnetics Research Letters, Vol. 22, 9-17, 2011


Excitation and propagation of a pulse electromagnetic wave in an open circular dielectric waveguide is considered. Partition of the pulse field into radiated wave, surface wave, and guided wave has been revealed and the corresponding physical effects are interpreted directly in the time domain. Namely it was shown that there is a precursor at the rod axis that propagates with speed of light in free space, it originates from the pulse surface wave that propagates along the rod surface and radiates into the rod in a Cherenkov like manner.
