“…Metasurfaces refer to a periodical combination of overlapped planar metallic and dielectric layers in sub-wavelength size, which have unique abilities to manipulate microwave signals at desired frequencies. They possess capabilities of power-conserving transformations [1], [2], cloaking [3], absorber [4], spatial filtering [5], polarizer [6], radar cross-section reduction [7], to name just a few. Among them, the frequency selective surfaces (FSS) focus on the transmission or reflection capability.…”

“…The harvested energy is then managed using a power management module [23]. However, most of the energy harvesters reported in the literature are designed to harvest only TE or TM-polarized RF energy at a fixed frequency, and the harvesting efficiency decreases significantly with increasing incidence angle [24,25]. This means that the operating frequency of peak efficiency varies with the angle of incidence.…”

Metasurface energy harvesters (MEH) lessen the dependence of wireless communication devices on batteries or other external power sources by capturing untapped electromagnetic energy in the surroundings. In this paper, we propose a multi-frequency and multi-mode microwave metasurface for efficient radio frequency (RF) and microwave energy harvesting in this paper. The MEH is comprised of a sub-wavelength resonant ring array, which can harvest RF energy in both Wi-Fi and 5 GHz bands. A feeding network is designed to integrate the TE and TM wave energy collected by the MEH into two separate networks that each gather AC energy and deliver them to the resistive loads. In terms of the simulation’s results, the efficiency of energy harvesting at frequencies of 2.4 GHz, 3.1 GHz, as well as 3.6 GHz is 91.3%, 88.9%, and 73.9%, specifically. We manufactured a 6×6 array sample and conducted experiments utilizing a microwave anechoic chamber. The simulation results and results from experiments were approximately identical. The proposed design has potential applications in various fields, such as efficient wireless energy harvesting (WEH) systems, self-powered devices, which has a significant potential on the environment and the energy sector by reducing carbon emissions and reducing reliance on non-renewable energy sources.

“…Moreover, current studies focus on energy harvesting at broadband [13], [14] and high frequency band [15], but these work bands are not suitable for daily application. Among the recent related research, few designs can simultaneously achieve more than two operating frequency bands, basically working at a singleband [16], [17], [18] and dual-band [19]. In addition, due to the high impedance characteristics of structures such as split ring resonators (SRR) [16], [17], [20], the load resistance used to match some metasurface design is very large.…”

“…In addition, due to the high impedance characteristics of structures such as split ring resonators (SRR) [16], [17], [20], the load resistance used to match some metasurface design is very large. This makes the width of the microstrip line corresponding to large resistance much smaller than the processing precision and it will be quite difficult to match these metasurfaces to the rectifier with 50 input impedance [18], [21].…”

A multi-band and polarization-insensitive metamaterial is proposed to harvest electromagnetic energy efficiently in three frequency bands. Based on a square resonant ring and cross resonant structure, a metamaterial is designed to achieve high energy harvesting efficiency of 81.2%, 93.3% and 93.5% at 2.45 GHz, 4.0 GHz and 5.8 GHz, respectively. The overall structure consists of an 8 × 8 periodic array of meta-cells with two vias loaded by two 50 resistors, an impedance matching network and a rectifier circuit. Results show that the simulated rectification efficiency of rectifier circuit reaches 69.2%, 58.8% and 52.1% at 2.45 GHz, 4.0 GHz and 5.8 GHz, respectively, when the incident power is 5 dBm. The measured harvesting efficiency (RF-DC) is found to be 51.6%, 54.2% and 58.7% with the TE polarization and 50.6%, 53.7% and 58.6% with the TM polarization incidence at the three operating frequency bands, respectively. Although the incident power is reduced to 0 dBm, the energy harvesting efficiency can still reach more than 42% in both TE and TM polarizations. Therefore, it is shown that the energy harvesting system can maintain high efficiency under different polarizations in a wide power range.
