This novel antenna developed by CityU has high gain and wideband characteristics, and can be used as an element for constructing antenna arrays. Bandwidth and gain enhancement techniques cannot usually be implemented at the same time, since the structure may become very complicated or bulky. The inv.....

EMI filters installed in electrical and electronic devices prevent electromagnetic noises generated by the devices from entering the mains power supply. The miniaturization of electronic devices and components means that smaller EMI filters of high efficiency are called for. The new filter comprises.....

This invention presents light maximization method for LED systems. Derived from a general theory that links the photometric, electric and thermal behaviours of LED systems together, the method provides the rules to design LED systems with maximum light output. Its main contribution is to provide cle.....
