“…Due to the increased in-plane rate, light traveling freely along the metal-dielectric barrier is related to the SPP modes. As a result, the wave vector of the SPP can be expressed as follows [21]: The incident radiation's wavelength is λ, the array's angle of incidence is θ, while m and n are integers determining the lattice vectors in the x-and y-directions, respectively with…”

Extraordinary Optical Transmission Plasmonic Color Filters (EOT-PCFs) with nanostructures have the advantages of consistent color, small size, and excellent color reproduction, making them a suitable replacement for colorant-based filters. Currently, the color gamut created by plasmonic filters is limited to the standard red, green, blue (sRGB) color space, which limits their use in the future. To address this limitation, we propose a surface plasmon resonance (SPR) color filter scheme, which may provide a RGB-wide color gamut while exceeding the sRGB color space. On the surface of the aluminum film, a unique nanopattern structure is etched. The nanohole functions as a coupled grating that matches photon momentum to plasma when exposed to natural light. Metals and surfaces create surface plasmon resonances as light passes through the metal film. The plasmon resonance wavelength can be modified by modifying the structural parameters of the nanopattern to obtain varied transmission spectra. The International Commission on Illumination (CIE 1931) chromaticity diagram can convert the transmission spectrum into color coordinates and convert the spectrum into various colors. The color range and saturation can outperform existing color filters.

Extraordinary optical transmission (EOT) behaviour is investigated in a subwavelength plasmonic nanostructure, consisting of a gold film perforated with a square nanohole array and deposited on a silicon dioxide substrate. The essential aspect of the proposed structure is the periodic disorder that enables broadband transmission peaks in the visible and near-infrared region and reduces the structure's size, which mainly arises from the excitation of localized surface plasmon resonances (LSPRs). Optical cavity modes formed in the nanoholes and the hybridization of plasmon modes. Further, the performance of the proposed nanostructure as a plasmonic sensor is analyzed by increasing the index of refraction of the local environment; the EOT exhibit remarkable refractive index sensitivity of up to 944 nm/RIU, a figure of merit of 9.25 and a contrast ratio of 47% are realized. The proposed structure has some practical significance for designing low-cost and effective sensing devices.
