Broadband wireless power transfer in weak-signal and multipath environments

In this paper, we study improved techniques for wireless power transfer (WPT) in weak-signal and multipath environments. We present a primarily theoretical and analytical approach to the problem of improving the efficiency of WPT systems by focusing on the nature of the transmitted signals and the interaction of the signals with the environment. This work also has many practical implications, particularly for ultra-wideband radio-frequency identification systems and for both sensing and power broadcasting in indoor environments.
