“…A helical antenna exhibiting resonating wideband operation around 28.3 THz is realized. The illustrated design parameters of the nanoantenna in Figure 1(a and b) are further optimized from [14] structure for enhanced field enhancement characteristics. Table 1 lists the optimized geometrical parameters of Figure 1(a) log-spiral IR antenna.…”

“…MIIM rectenna, or metal-insulator-insulator-metal rectenna, is an advanced type of rectifying antenna that offers several advantages over traditional MIM rectennas [14,15]. These advantages include (i) higher efficiency because of more absorption of electromagnetic energy, (ii) better impedance matching and thus less energy loss during conversion with higher rectification efficiency or responsivity (iii) better tolerance to fabrication variations, (iv) more stable output for consistent output power generation, (v) wider operational frequency range, (vi) potential for integration with other semiconductor materials because of an additional insulator layer, and (vii) low power consumption [14,16,17].…”

“…A circular MIIM plasmonic resonator with indium tin oxide (ITO) and SiO2 as gating material with a DC biasing of metasurface structure is reported in [19] for the enhanced transmission characteristic at 1650 nm. Recently Yahyaoui et al [14] discussed the field enhancement and rectification characteristics of a logspiral-based MIIM rectenna only. The existing literature primarily focuses on individual MIM/MIIM structures or metasurface analysis, leaving a gap in the comprehensive characterization of the combination of MIIM structures with integrated metasurfaces.…”

“…The study also thoroughly analyzes the impact of different MIIM materials configurations on the received electric field and rectification parameters (I/V characteristics, resistivity, and responsivity) for four symmetric and asymmetric metals combinations (gold (Au), aluminum (Al), silver (Ag), and copper (Cu)) and four pairs of insulators (aluminum oxide -copper oxide, aluminum oxide -titanium oxide, aluminum oxide -zinc oxide, and titanium oxide -copper oxide), with and without the added meta lens. These pairs of insulators are selected based on their superior performance from the analysis of ten different insulator combinations in a previous study [14]. The numerical analysis is carried out using CST microwave studio software for the frequency range of 28 to 29 THz.…”

This work presents the design and analysis of a novel metal-insulator-insulator-metal (MIIM) rectenna with an added meta lens on top of it for efficient and robust infrared (IR) energy harvesting at 28.3 THz. To ensure maximum transfer of the captured IR radiations by an antenna with better impedance matching, the log-spiral antenna terminals are used as rectenna electrodes while two different insulators are placed between its feeding terminals to form the MIIM rectenna. A split ring-based resonating metasurface is designed and placed on the top of the MIIM rectenna to focus the incoming electromagnetic radiations. The characterization of the MIIM rectenna with added meta lens, in terms of absorbed E-field, is performed for the four different work function metals (gold aluminum, silver, and copper) as well as four combinations of aluminum oxide, titanium oxide, zinc oxide, and copper oxide as insulators. The focusing of illuminating IR radiations by the integrated meta lens to the rectenna structure enhances its field-capturing characteristic by more than 400% as compared to conventional structures. In addition, the proposed design shows improved rectification properties in terms of better impedance matching and rectification efficiency, particularly for the best configuration of Au-Al2O3-Cu2O-Cu rectenna with added metasurface. Future applications of this study include the development of efficient IR energy harvesting systems for remote sensing, wireless communication, and other IoT devices.
