An ultra-compact pulse compressor for generating ultrawideband short pulses is proposed and tested. The proposed pulse compressor consists of a thin copper-coated dielectric laminate to form an ‘ultra-compact’ reverberant cavity, where a time-reversal-based input pulse is compressed into an ultrawideband short pulse. The proposed pulse compressor is validated via numerical simulation and measurement, and results show that a short pulse is generated with a peak gain of >10 dB.
