Design and Modeling of a Dispersive Pulse Compressor based Frequency Tunable HPM System
Abstract
The potential for increasing the range of frequencies which can be compressed by a dispersive, hollow, helically corrugated, waveguide has been investigated. A three-fold helical corrugation was investigated since initial analysis revealed that five-fold corrugation schemes, although certainly supporting higher power levels, would be difficult to extend in frequency range. Analytical methods, time domain and eigenmode computer simulations were used to predict the dispersion of the helically corrugated waveguide for the two distinct circular polarisations (which exist due to the chirality of the waveguide). These were found to be in excellent agreement with the experimental measurements. Critically the measurements showed that the uncoupled polarisation had almost no modification to its dispersion when compared to the behaviour of a smooth waveguide.
