Abstract :
The use of a helically corrugated waveguide as a dispersive medium for microwave pulse compression is presented. The helically corrugated waveguide has a large variation in group-velocity with frequency in a region far from cut-off. This compressor does not suffer from reflections associated with operation near cut-off and therefore can be used at the output of a high-power microwave device.
