A plasma photonic crystal operating as a notch filter at 157 GHz (vo) has been demonstrated. Comprising a 5 × 10 array of microplasma jets, having a pitch and jet diameter of 1 mm and 400 μm, respectively, this two-dimensional plasma crystal exhibits an unexpectedly narrow stopband (δV = 1.0 GHz (FWHM) = 0.6% -o) and a maximum, time-averaged attenuation of 5% at 157.0 GHz. Simulations accurately predict the position of line center, and the assumption of a time-averaged electron density of 3 × 1013 cm-3 is necessary for the predicted magnitude of peak attenuation (at 157 GHz) to be in agreement with experiment. Reconfigurable plasma photonic crystals, synthesized from microcavity plasmas and providing electromagnetic functionality in the 100 GHz1 THz spectral region (300 μm < λ > 3 mm), are now feasible.
