All-Dielectric Frequency Selective Surfaces for High Power Microwave Applications

This effort will develop an all-dielectric frequency selective surface (FSS) technology for high power microwave applications. It will be highly compact and capable of operating at much higher power than metallic designs. All-dielectric FSSs are much less well studied despite their benefits for high power applications. The work proposed here will contribute significantly to this field and advance the state-of-the-art in FSS designs for ultra-high power. BENEFIT: The all-dielectric frequency selective surfaces developed during this effort will be capable of operating at much higher power than their metallic counterparts and be safer to handle in high voltage and high field environments. Applications include directed energy weapons, EM pulse protection, radar, and communications. Technology could be deployed on aerospace vehicles, ground vehicles, naval vessels, or ground facilities.
