Abstract Recently, the emergence of a new class materials called ‘MXenes’ has expanded application nanostructures in optical devices, such as sensors, solar cells, saturable absorbers, and perfect absorbers. MXenes possess combination plasmonic characteristics high electrical conductivity, making them an unrivaled choice for designing In this paper, nanostructure composed common MXene, Ti 3 C 2 Tx is introduced, coupled with silver (Ag) grating embedded within dielectric layer to enhance response achieve absorber visible region. To optimize performance nanostructure, various geometrical parameters are fine‐tuned, including radius, center, width structure, thickness layer, layer. By carefully adjusting these parameters, absorption structure significantly increased, reaching up 99.9% full at half maximum (FWHM) 53 nm

Abstract To optimise the production of energy and minimise loss concerning availability green energy, especially solar a number sun light absorber prototypes composed various materials were examined. Tungsten MXene serve as components in Hexagonal with Square-shaped Resonator Metamaterial MXene-based Solar Absorber (HWSRMMSA), resonator hexagonal square form. The substrate recommended HWSRMMSA was SiO2, contrast to bottom layer Fe. Polarization is important for this ultra-wideband HWSRMMSA, which has wide bandwidth 2020 1140 nm 91% 96% absorptance at 200–4000 wavelength. Permittivity characteristics, refractive index, permeability among negative metamaterial consequences that expanded reliability absorptance. According calculation, maximum possible R2 value 0.999551 parameter modification ML (machine learning) model, using liner regression aims reduce simulation duration by quarter within comparison previous techniques while lowering other requirements. Finally, previously described used observe compare, Electric intensity studied described. Because its outstanding absorptance, surface plasmon resonance ultra-broadband, been utilized water heaters.
