It's easy to start your application.
Research in areas related to applied physics span topics in advanced materials, integrated photonics and opto-electronics, nano-fabrication, and new device concepts. Some of this focuses on the fabrication and characterization of nano-microtoroidal silicon-based resonators that exhibit extremely high Q factors. These photonic elements offer potential for a variety of applications, including chemical and biomedical sensing.
Other new directions being pursued seek to exploit these devices in arrays to create surfaces comprised of artificially-created materials (metamaterials) that can be used to scatter microwave radiation using optical and electrical signals to control the energy scattered from or captured by the surface. It is envisioned that this work can impact defense (e.g. radar cross section), commercial (e.g. automobile collision avoidance radar), and biomedical (e.g. irradiation of tissue) applications.
