Aerosol-Jet Printed Quasi-Optical Terahertz Filters

Abstract

This paper presents the design, simulation, and characterization of metamaterial-inspired terahertz filters, fabricated by aerosol-jet printing. Filters are designed for operation at 230, 245, and 510 GHz, for both band-pass and bandstop operation. Operation of each printed filter is compared to structures fabricated from copper metal using a photolithographic process. Each of the aerosol jet printed filters are found to have performance comparable to those fabricated using lithographic techniques, demonstrating the applicability of aerosol-jet printing to the fabrication of components operating in the terahertz regime.
