Smart wireless power transfer operated by time-modulated arrays via a two-step procedure

none3noThe paper introduces a novel method for agile and precise wireless power transmission operated by a time-modulated array. The unique, almost real-time reconfiguration capability of these arrays is fully exploited by a two-step procedure: first, a two-element time-modulated subarray is used for localization of tagged sensors to be energized; the entire 16-element TMA then provides the power to the detected tags, by exploiting the fundamental and first-sideband harmonic radiation. An investigation on the best array architecture is carried out, showing the importance of the adopted nonlinear/full-wave computer-aided-design platform. Very promising simulated energy transfer performance of the entire nonlinear radiating system is demonstrated.openMasotti, Diego; Costanzo, Alessandra; Rizzoli, VittorioMasotti, Diego; Costanzo, Alessandra; Rizzoli, Vittori
