Abstract

One interesting method of microwave pulse compression is passive-frequency-based microwave pulse compression where a dispersive medium is used to compress a frequency swept pulse. Oversized circular waveguide having helical corrugation supports eigenmodes that are suitable for pulse compression for frequency modulated input pulse is as shown by Brat et.al. [IEEE Trans. Plasma Sci., vol. 33, no.2, pp. 661-667, 2005.]. In this paper, theoretical studies on microwave pulse compression in helically corrugated waveguide is presented. The numerical results show a eleven fold peak power compression.
