This letter proposes a reconfigurable scheme of wireless power transmission in fully enclosed environments. The proposed scheme includes one transmitting element and multiple parasitic elements. Field distribution in the fully enclosed environment is reconfigured by switching the parasitic elements' termination between open and short, with the aim of delivering wireless power efficiently to a receiver whose location is not fixed or not known. Experimental results demonstrate that, via tuning nine parasitic elements at frequency 425 MHz, it is possible to achieve power transmission efficiency greater than 70% when a wireless power receiver changes its location within a 0.4 m by 0.6 m region inside a 1-cubic-meter cubic box.
