The technology of manufacturing metal-dielectric photonic crystals for THz and millimeter ranges by 3D printing

The article considers the possibility of using 3D printing technologies to manufacture the photonic crystal structures of THz and millimeter ranges. This approach consists of the manufacturing of a polymer photonic crystal matrix by 3D printing based on photopolymerization, followed by filling the voids of the matrix with fusible material that reflects well in the terahertz range (the Wood alloy was used).
