Transformers are used for energy and signal transfer and for providing electrical isolation. CityU researchers have developed a coreless PCB-based transformer that does not require a transformer core, thereby reducing production cost and simplifying the automated manufacturing of transformers. The i.....

CityU inventors have developed a new dielectric waveguide known as dielectric microstrip line (DML). Designed for low-cost millimeter waves and Terahertz front-end systems, the DML does not have any metal conductor, and consists of three dielectric layers. It also has a planar structure that can be .....
