A novel technology for the measurement and surface reconstruction of a 3D image of an object is developed. The method proposed comprises the projection of a pattern onto the surface to be imaged, the examination of distortion incurred on the pattern by the surface, and the conversion of distortion b.....

The invention relates to circularly polarized (CP) antennas with grating dielectric elements acting as a polarizer to convert a linearly polarized omnidirectional radiation pattern from a monopole antenna to an omnidirectional CP radiation pattern. A prototype with parallelepipeds, having a very wid.....

To isolate micro-particles, CityU researchers have developed a method that makes use of moving optical tweezers in the microfluidic chip. The design of the sorter is based on dynamic fluid and light patterns, which enable the sorting of micro-particles, such as cells, from a small amount of samples .....
