The objective of this Open BAA is to encourage a flow of supplementary and/or complementary technologies for electromagnetic metamaterials. Such technologies may include active electronic matching networks, frequency selective structures, and periodic structure with engineered dispersion, including photonic band-gap materials, acoustic metamaterials. Innovative advancements in using metamaterials and/or complementary technologies that leverage commercial economies of scale are highly desired. The areas of focus are Radio Frequency (RF), Optical, Acoustic and Bio-Related Metamaterials. ONLY WHITE PAPERS ARE BEING REQUESTED AT THIS TIME.
