2017-12-12 Journal of Applied Physics 122, 083104 (2017); doi: 10.1063/1.5000239 Propagation of a nanosecond microwave pulse through a photonic crystal placed into an X-band
waveguide is investigated. The nanosecond pulse is produced via shortening of the microsecond
microwave pulse by the plasma electromagnetic band gap structure, which is formed in the wave-
guide by microwave breakdown ignited discharges inside three neon-filled glass tubes. Measured
delay time for nanosecond microwave pulse propagation through the photonic crystal is about 23 ns
that is in good agreement with the value obtained by numerical simulation. This time delay value
corresponds to the group velocity of microwave pulses in the photonic crystal v gr ~ 0.11c, where c
is the speed of light in vacuum. Download:
