Abstract
As the number and magnitude of radiated electromagnetic fields from electronic devices increase, the radiation of electromagnetic field must be carefully considered because it can cause physiological harm on human body. It may also lead to malfunctioning of other electronic systems. Since OLEV involves power of over kilowatts, the transmitted and received power and the electromagnetic compatibility problem require careful considerations. Various shielding methods are presented, including passive and active shielding. A reactive shield is also introduced and explained as a possible solution for reduction in magnetic field in OLEV applications.
