Optical and Electromagnetic Waves


Optical and Electromagnetic Waves (OEW) Lab studies research topics that aim to improve electrical, electronic, and telecommunication systems in speed and reliability. Our research is related to specific design technology to intentionally control and reduce unintentional electromagnetic waves, or electromagnetic noise, generated by electrical, electronic, and telecommunication equipment. Such design technology is called EMC design. EMC is short for electromagnetic compatibility and means the ability of an equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable disturbance to anything in that environment. EMC consists of two aspects, EMI (electromagnetic interference) and EMS (electromagnetic susceptibility). The former is the ability that a system cannot interfere with other systems or subsystems. In contrast, the latter is the one that system must continue to operate correctly in the presence of interference from others or transient.
