A note on the use of dust plasma crystals as FIR/submillimeter filters

The use of dust plasma crystals as filters of electromagnetic waves in the far-infrared or submillimeter wavelength regime is investigated theoretically. The analysis is based on previous analyses of crystalline colloid array filters that make use of dynamical diffraction theory coupled with theory for electromagnetic wave scattering from small spheres. Theoretical bandwidths, attenuation factors, and limits on wave intensity are considered.
