Real-time tuning of the propagation properties of the crystals in the 110-170 GHz spectral interval has been achieved in such photonic crystals by changing the refractive index of the microplasma at electronic speeds. Different structures can be achieved in such crystals by filling each column of a crystal with different materials such as metals, dielectrics, and plasma. Interesting phenomena such as plasma-induced transparency, mode splitting, and Fano-like lineshapes are observed from different crystal structures under different experimental conditions.
