Abstract
A system for wireless power transfer (WPT) is described. The WPT system may be used for charging of electric vehicles or other mobile platforms. The WPT system includes a gap waveguide base including a conductive waveguiding structure and a bandgap structure along at least the lateral sides of the waveguiding structure. The WPT system also includes a charging plate separate from the gap waveguide base. The charging plate includes a conductive plate having a receiving structure for receiving the electromagnetic field from the gap waveguide base through an air gap. The disclosed WPT system enables propagation of an electromagnetic field through the air gap, including electromagnetic fields in the very high frequency (VHF) band.
