Terahertz waves transmission in 3D printed photonic crystals

Three-dimensional printing technologies are attracting more attentions to develop devices for effective control and manipulation of electromagnetic waves. Due to the limitation of resolution of apparatus, 3D printing technologies were originally applied to the radio-frequency. Thanks to the continuous innovation of hardware, materials and processes in the 3D printing, structures with smaller minimum features can be fabricated, opening up the possibilities of creating 3D-printed components for the THz ranges [1].
