摘要：

A star-shaped indium tin oxide-based transparent plasmonic nano-antenna is designed and studied for nanophotonic applications using a silicon dioxide substrate. The dispersive properties and epsilon near zero wavelength of the indium tin oxide and silicon dioxide are analysed using the Drude and Lorentz formulas. The design of the nanostructure is optimised using CST Microwave Studio through the design parameters such as length, width of the conducting patch and substrate. The optimised results exhibit that the proposed transparent conducting patch is operating at 29.87 THz with a gain of 7.04 dBi. Further, the S11 coefficient of the proposed antenna is −41.84 dB with a bandwidth of 4 THz at the resonance. The proposed transparent antenna exhibits field enhancement factors of 375 and 240 for E and H fields, respectively. The nanocircuit of the transparent antenna is derived and the simulated results are validated using the proposed model. The designed transparent antenna is suitable to use in the nanophotonic integrated circuits since it exhibits plasmonic resonance characteristics. © 2025 Elsevier GmbH
