摘要：

- Wireless power transfer has become a trending research area for remotely transferring power. This paper presents the numerical simulation study of selective wireless power transfer to closely spaced wireless sensors embedded in reinforced concrete. A selective microwave wireless power transfer is achieved at a 10 mm separation between tightly-coupled monopole antennas (wireless sensor antennas). Both tightlycoupled wireless sensors operate at 2.45 GHz, hence beating the diffraction limit at lambda /12 with the incorporation of additional scatterers in the reinforced concrete wireless power transfer to wireless sensors with subwavelength separation (closely spaced) to which one structures creates some randomness serving as scatsensors embedded in concrete.
