Passive Pulse Compression Using a Lossless Dielectric Loaded Waveguide

This paper presents a new method to achieve passive pulse compression using a lossless dielectric loaded waveguide (DLW). The method demonstrates an obvious performance in controlling the dispersion characteristics of the DLWs. Efficient pulse compression in a specific frequency range is achieved by varying the radius and thickness. In the simulation, the compression factor of 85.6 is obtained by compressing a linear frequency-modulated pulse with a duration of 20 ns and a frequency range of 34.8-39.8 GHz into a Gaussian-envelope pulse.
