Completed TRL 3 (started at 2, targeting 3)
Our team’s goal for this project is to continue development of COC based coupler components for waveguide embedded circuitry in instruments operating at 500-750 GHz (WR 1.5 band) and demonstrate COC based dichroic filters as frequency selective surfaces at 325 and 680 GHz. The work includes the resonator test structures for measuring the complex dielectric function of a new COC formulation with a higher glass transition temperature for extended device temperature operation.
Miniaturized, flexible, custom COC components are not commercially available at the high frequencies of interest for many Earth Science and Planetary instruments. We will fabricate a variety of COC components using a brand new spin-on COC formulation extending COC component device temperature operation. COC based components can be utilized for remote sensing receiver systems for Planetary exploration such as New Frontiers missions targeting Enceladus and Venus. Specifically, the COC couplers may greatly benefit V-WISHES and WISHES (Wideband Imaging Submillimeter Heterodyne Spectrometer). As for Earth Science applications, the dichroic filters are specifically targeting the EVI PolSIR instrument (Polarimeter Submm-wave Ice Cloud Radiometer).
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
