Patched-Wall Quasistatic Cavity Resonators for 3-D Wireless Power Transfer

The Takeaway
Previous 'wireless rooms' required a massive conductive pillar in the center to distribute power, making them impractical. This new 'patched-wall' system hides the technology inside the room's surfaces, allowing devices to charge at high efficiency anywhere within the 54-cubic-meter space while keeping the room completely empty.
From the abstract
Traditional wireless power transfer (WPT) systems are largely limited to 1-D charging pads or 2-D charging surfaces and therefore do not support a truly ubiquitous device-powering experience. Although room-scale WPT based on multimode quasistatic cavity resonance (QSCR) has demonstrated full-volume coverage by leveraging multiple resonant modes, existing high-coverage implementations require obstructive internal conductive structures, such as a central pole. This letter presents a new structure,
