Reconfigurable transmittance spectra and wave group velocities in 110 – 170 GHz frequency regimes are shown by changing plasma parameters and photonic crystal spatial structure. A Dynamic mode-splitting around 131.8 GHz in transmittance spectra is experimentally and theoretically studied in this work. The coupling strength can be tuned by changing the AC power supplies on the plasma which is changing the electron densities and permittivity in the plasma. The coupled-mode theory was used to calculate the coupling strength as well as transmittance spectra. It can be seen that theoretical results fit well with the experimental results.
