Abstract :
Pulse signal propagation in an open circular dielectric waveguide was considered in Time Domain. The field partition into a guided wave, a radiated wave, and a pulse surface wave was observed. A precursor creation by the pulse surface wave in the dielectric waveguide is shown. In order to study long-time behavior of this wave a moving frame with BOR-FDTD method was used. A pure pulse wave can be excited by “moving” sources (consecutively exited along the waveguide) that was used for studying such wave structure by its own. Diffraction of this surface wave by a conical rod tip was simulated and analyzed as well.
