Web15 de jan. de 2024 · By applying the optical nanocircuit concepts to metasurfaces, an effective route to locally control light transmission over a deeply subwavelength scale is proposed, which may lead to large improvements in the manipulation of optical transmission and processing of nanoscale optical signals over conformal and Si-compatible … Webthat metasurfaces also offer new unparalleled capabilities for decreasing the overall dimensions of integrated optical components and systems. We propose an original approach of embedding a metasurface inside one of the most fundamental optical elements – an optical cavity – to drastically scale-down the thickness of the optical cavity. Web20 de set. de 2024 · In this paper, multiple Fano resonances preferred in the refractive index sensing area are achieved based on sub-wavelength metal-insulator-metal (MIM) waveguides. Two slot cavities, which are placed between or above the MIM waveguides, can support the bright modes or the dark modes, respectively. Owing to the mode … high heel shoe sofa
