In this paper, we propose the use of metasurfaces to enhance evanescent wave coupling to improve the wireless power transfer (WPT) efficiency of multiple receivers. A 4 × 4 negative permeability metasurface is designed and placed between the transmi

A broadband omnidirectional dual-polarized antenna is proposed in this paper. The basic idea of the antenna is the development of cylindrical conformal array. By using a new designed double patch structure antenna element, both polarization ports of
