N2 - We present novel strategies to mitigate radiated emissions through apertures and enclosures using electromagnetic bandgap (EBG) structures. The proposed technique comprises loading EBG surfaces immediately around the apertures opening in order to suppress surface currents. Numerical full-wave simulations are presented to demonstrate the effectiveness of the EBG surface. In fact, by using EBG structures, more than 20-dB reduction in field leakage is achieved in the near-and far-field radiation without affecting the aperture size. The proposed technique is compared against unloaded aperture and other loaded apertures with lossy resistive sheets. A practical case study from real-world environment is discussed and the concept is validated using measurements.
