This research involves multidisciplinary work in the application of various engineering and scientific disciplines with the purpose of exploration, discovery, and exploitation of basic materials properties to design and control the interaction of electromagnetic waves with matter. Our aim is to develop new, improved multifunctional materials, technologies, and devices to operate in complex electromagnetic environments and environmental conditions. Specifically the major objectives of this work are to design, simulate, and fabricate subwavelength structures, plasmonic, and micro-/nano-resonant structures and devices for optical, photonic, and RF applications. Examples of such structures include metallic media, semiconductor patterned structures, Fano-resonant antennas, plasmonic metamaterials, resonant nanocavities, etc. Theoretical models and computational simulations will be developed for these structures to describe the electromagnetic behavior, as well as to optimize the material systems and devices. The resulting fabrication techniques and modeling methods will lead to new technology for devices that can be tailored for specific detection schemes for optical signal enhancement and detection. It is anticipated that the modeling/fabrication/characterization efforts will be iterative towards the development of a highly sensitive platforms that are robust and wavelength scalable.
