In this paper, the design of a graphene arrowbowtie nanoantenna mid-IR energy-harvester to power IOT wireless sensor is presented. For the first time, a sensitivity analysis of the mid-IR nanoantenna resonant frequencies in terms of different graphene number of sheets and chemical potential (𝝁 𝒄𝒑 ) without substrate and on a two-layer substrate composed of SiO2 and Si, is carried out. The obtained simulation results by 3D CST 2020 are useful to design an efficient infrared nanorectenna, composed of the nanoantenna and a rectifying MIM diode inside the gap. The analysis of the complete energy-harvester (EH), composed of an NxM nanorectenna array, a low-pass filter, and a DC-DC converter, is reported. With an output voltage value of 3.3 V, an output current of 10 mA, and an area of about 11,57 mm 2 , the proposed 1964x65467 nanorectenna array-based infrared energy harvester array represents an optimal solution to powering IoT wireless sensors.

“…That rectifier converts the received signal to DC power and produces electricity. Nanoantennas are used to absorb electromagnetic wave radiation especially unused part s of solar radiation (IR region) and the thermal radiation from objects and convert it to electric current and vice versa [4][5][6][7] Plasmonic nanoantennas, consisting of nanoscale gaps between neighboring metallic nanoparticles, have recently been of great interest due to their ability to support a highly efficient, localized surface Plasmon resonance (LSPR) which is an effect that produces noted peaks in extinction spectra, and highly confined electromagnetic fields [8][9][10]. The strong field enhancements make them play a crucial role in many technologies and applications, including sensing application of plasmonic in MIR senasing [11][12][13][14], super absorption [15][16][17][18], steering and focusing [19][20][21][22] Since silver and gold are used in most plasmonic devices, they can only provide high confinement when employed near their plasma frequency [6].…”

Due to the high need for renewable energy on a worldwide scale, significant research ha s been done on how to use solar energy as a source of free and clean energy. The energy produced is mostly released as electromagnetic radiation with a spectral range of 0.2 to 3 m. New technologies are being developed to harvest this energy while overcoming the limitations of conventional PV devices. These new devices are called nano-antennas (rectenna). Nanoantennas are used to absorb electromagnetic wave radiation especially unused parts of solar radiation (IR region) and the thermal radiation from objects and convert it to electric current and vice versa. Here, a novel design of an "E"-shaped nano-antenna for energy harvesting is introduced and analyzed by using the three-dimensional (3D) finite-difference time-domain (FDTD) method. The key issue in the design of an “E"-shaped nano-antenna for energy harvesting is based on the excitation of surface plasmon polaritons (SPP) through the doped silicon arms of the E shape placed on an Al2O3 substrate to obtain wideband behavior in IR region. In this paper, doped silicon was used instead of noble metal as a plasmonic material with optical resonances in the infrared. The width and length of doped silicon arms are v aried to get the best performance. Doped nanocrystals (NCs) have received more attention lately because through doping the free carrier densities can be changed gradually and active tenability can be achieved.

A novel, polarization-independent, wide-angle reception Chand-Bali nano-antenna is proposed. An adjoint-based optimization algorithm is used to create the same resonance at both linear polarizations of the incident radiation. The nano-antenna optimal parameters reveal that two hot spots with a strong field enhancement are created. These hot-spots could be integrated with metal–insulator–metal (MIM) diodes to form a rectenna for infrared (IR) energy harvesting. The metallic resonators allow for selecting several materials to facilitate the fabrication of the nano-antenna and the MIM diode. The Chand-Bali-based IR rectennas are investigated and simulations demonstrate an improvement of more than one order of magnitude in efficiency compared to ones using traditional nano-antennas.
