The invention is a hybrid photovoltaic/thermal collector that converts solar energy to electrical energy and thermal energy by using photovoltaic cells and thermal energy collector respectively. This solar collector comprises a layer of photovoltaic (PV) cells laminated to the surface of a thermal c.....

The Doherty power amplifier (DPA), a component used in wireless communication devices, has two sub-amplifiers operating at different power levels. The differing bias conditions usually lead to unbalanced current driving ability and efficiency reduction. Unlike common techniques employed to achieve i.....

The wideband active quasi-circulator developed by CityU allows simultaneous transmission and reception of signals from an antenna to different transmit and receive path signals without using separated filters. It enables a single device to operate in multiple bands and replace the separate blocks of.....

The device facilitates the fabrication of ME laminate configuration by using a flextensional cymbal located between two terfenol-D plates. A giant magnetoelectric effect in a heterostructure is achieved by clamping an ME terfenol-D alloy actuator and a cymbal-type piezoelectric single crystal-brass .....
