A dual-band (2.45 and 12 GHz) and wide-angle MS (short for metasurface) for RF (short for radio frequency) energy harvesting is proposed in this research. This structure can maintain a high efficiency over 90% at 2.45 GHz for electromagnetic wave harvesting as conventional ones, and can operate in another frequency band with efficiency of at least 90%. For verification, a prototype is fabricated and measured in an anechoic chamber. The experimental results corroborate the proposed MS performs well with the efficiency of more than 80% for wide-angle incident waves in all frequency bands. Isolated by a wide band between both resonances points, the MS structure can provide alternative sources to wireless sensor network (WSN) without mutual interference.

“…Thus, making it suitable for variety of applications. They have been widely studied in the field of optics and have been used to create a wide range of functional devices such as waveplates [1][2][3], polarizers [4][5][6][7][8], and beam shapers [9][10][11][12][13]. One of the key advantages of metasurfaces is that they can be used to create highly compact and lightweight devices that can be integrated into a wide range of systems.…”

In this reported work a single feed, miniaturized, dual layer, and low profile antenna is presented for 1.575GHz frequency band. The proposed antenna offers high gain, lower noise bandwidth, with better sensitivity and range. The ground choke technique is used for back lobe suppression. The prototype is fabricated on FR 4 substrate using manual fabrication technique. This offers an inexpensive and readily available fabrication. Therefore, fabricated antenna is small size, low cost, easily fabricated and tested for satellite communication. The antenna comprises of two layers, containing a patch radiator and a Metasurface layer with 3x3 rectangular ring resonators. The layers are separated using foam with a 12mm width. The proposed prototype is radiating at 1.575GHz and 2.33GHz with an overall dimension of 85.6 x 68.4 x 15.204 mm. The developed antenna provides a gain of 5.9 dBi. The simulated results are verified using VNA and anechoic chamber testing. Moreover, the developed antenna has been successfully tested for L-Band Satellite communication in real time scenario without any LNA. Higher Gain due to Metasurface increase the efficiency of the system. The promising results indicate the aptness of the developed antenna for real-world applications of L-Band and S-Band.

In this paper, the different research papers are studied and comparatively analyzed to carry out the simulation based survey of various proposals for improvement to design Metarsurface based Perfect Absorber for GHz and THz frequency band for RF Energy Harvesting applications. Using a structure that can effectively absorb the most radiation is one of the biggest obstacles in reducing the impact of EM wave radiation. A perfect absorber may be created using variety of structures and materials with various specifications. Various structures are designed and simulated by different authors in variety of simulation softwares using useful parameters. Three distinct structures have been created, two of which were created using CST Microwave Studio and the third using HFFS for comparative study. A perfect absorber can be constructed for GHz and THz for dual band and multiband since the operating frequency range and band are not limited.
