Vehicles with wireless power transfer (WPT) is seen as one possible solution to overcome the limitations experienced in commercializing electric vehicles (EVs) due to limited battery power. However, one issue with vehicles with WPT is the power degradation that is experienced as misalignment occurs between the vehicle and the road. In order to overcome this problem, a system that can detect the misalignment...
Experimental tests of specific absorption rate (SAR) reduction on a mobile phone have been performed. To protect a human head from exposure to electromagnetic fields and comply with exposure guidelines, the electromagnetic bandgap (EBG) structures are inserted in a commercial personal communication services (PCS) mobile phone. The measured results demonstrate the movement of a hot spot and the reduction...
The partial placement of electromagnetic bandgap unit cells only near the sources of noise is proposed as a means of both suppressing the noise propagation and minimising the effects of a discontinuous reference plane. The simultaneous switching noise suppression performance of the proposed structure is verified and investigated experimentally.
