Discussion The proposed metasurface is highly efficient for harvesting EM energy in the Wireless Local Area Network (WLAN) band. The simulated and experimental results show that the metasurface has the properties of polarization insensitivity and high efficiency over a wide range of incidence angles.
The harvesting efficiency of the metasurface was calculated as η = PLOAD / PINC, where PLOAD is the total time-average power dissipated on the loads and PINC is the total time-average power incident on the metasurface. High Frequency Structure Simulator (HFSS) software was used to analyze the performance of the harvester.

With square-shaped metal via rings around the unit cell and one harvesting via near the center, this metasurface solves the problem of operation frequency shifts of the maximum efficiency when the incidence angle increases. This metasurface can harvest energy with a higher efficiency over an oblique incidence in both TE and TM polarizations.
A dual-band, polarization-insensitive, wide-angle metasurface array is presented in this article for electromagnetic (EM) energy harvesting in the UMTS-2100 band and Wi-Fi band. The metasurface unit cell is composed of two rings (each with four splits) nested in a centrosymmetric manner.
