Just say you’re doing high resolution of metamaterials for science. Materials resonant at the target radar band, because that wavelength is easier to manufacture/economically useful/etc. I think you’re more likely to find a job than trouble — SBIR has a bunch of grants in that area. (Last I looked.)
