The power amplifier, an indispensable component in most wireless communication systems, is inherently nonlinear. In view of the importance of video conferencing and internetworking features to the next generation of mobile terminals (e.g. mobile phones) as well as the demand for high data rate trans.....

Optically-induced dielectrophoresis (ODEP)-based bio-manipulation is a new paradigm for cell manipulation as it offers most of the capabilities of laser-based tweezers, but requires 100 times less optical power and with at least a 10-times reduction in system cost. Our research groups at City Univer.....
