Complex Dielectric Characterization and Forward Modeling of Lunar and Martian Materials for Artemis IV LDA and Mars Resource Reconnaissance

This requested short-duration task will complete essential modeling and calibration tasks supporting Agency‑level Moon‑to‑Mars priorities by finalizing complex dielectric permittivity and magnetic permeability analyses of key lunar (NWA 8687) and martian (NWA 16272) samples at 1 GHz using HFSS and previously acquired S‑parameter measurements. The effort will generate validated 3D dielectric tensor models across multiple sample orientations, enabling direct scientific connection to current RIMFAX GPR observations in Jezero Crater and future measurements from the Artemis IV “LDA” landed experiment. Deliverables include forward‑modeled dielectric properties, a near‑final research article for AAS/PSJ, and a ROSES‑2025 proposal focused on subsurface resource detection on the Moon and Mars. Support is requested for limited ETD engineering FTE and HFSS software access to complete these critical modeling tasks.

Validated 3D dielectric tensor models for Artemis IV-relevant lunar materials to evaluate loss tangent as a function of orientation for potential SAR or GPR radar performance predictions (subsurface resource detection); characterization of complex dielectric permittivity and anisotropy of lunar (NWA 8687) and martian (NWA 11288) samples; research paper for AAS/PSJ; ROSES-2025 proposal; loss tangent data to support U. Tokyo LDA team Artemis IV planning; advancement of waveguide-PNA concept with US Patent Pending status

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
