To provide a potential communications channel, HVAC ducts can function as electromagnetic waveguides; a 30-m read range has been achieved within a free space range of 6 m. ABSTRACT | In this paper, the use of hollow metal heating, ventilating, and airconditioning (HVAC) ducts as a potential communication channel between passive ultrahigh-frequency (UHF)(More)
Wireless power delivery has the potential to seamlessly power our electrical devices as easily as data is transmitted through the air. However, existing solutions are limited to near contact distances and do not provide the geometric freedom to enable automatic and un-aided charging. We introduce quasistatic cavity resonance (QSCR), which can enable(More)
