New techniques for imaging and analysis have been identified as key components of the evolution of diagnosti and therapeutic biomedical technologies. Advances in capabilities like early detection of disease, identification and study of living processes, pharmacology, and treatment contribute directly to the social well being of an aging population, to cost savings in healthcare, and to economic growth in environmentally friendly high-tech industries. In this proposal, we address a new class of imaging and analytical instruments that provide non-invasive and non-ionizing measurement in a small, portable, and low cost form factor. Our scientific focus is on key challenges in the generation, imaging, and detection of electromagnetic signals at Tera-Hertz frequencies, the frequency band between radio and visible light frequencies. Evidence suggests that biomedical analysis at these frequencies can reveal a wealth of new information for medical diagnosis and science.
