Abstract
In this collaborative STTR project between Vibratess LLC and UVA, we intent to conduct a combined theoretical and experimental study of plasmonic architectures for utilization with biological and chemical sensing in the THz spectral range. Plasmon Polariton (SSPP) devices that utilize metamaterials constructed of a conductor with sub-wavelength periodic structural features on it surface can tailor THz frequencies via the surface geometry. The objectives of this Phase I project are: 1) to define a new class of THz plasmonic nanostructures applicable for biosensing including focusing devices for enhancing interaction between the THz field and material under test, devices for coupling quazi-optical THz input/output radiation to waveguides, devices to transmit surface plasmon polariton propagation with minimal losses, and switches or modulators to allow for propagation control; 2) to demonstrate that these highly effective components for spectroscopy-based sensing can be implemented using relatively simple nano-manufacturing techniques; 3) to develop a conceptual design of an integrated chemical/biological spectroscopic sensor based on the THZ plasmonic nanostructures.
