Web25 de jan. de 2024 · We propose a heat-reconfigurable metasurface composed of the silicon-based gold grating. The asymmetric Fano-like line shape is formed due to the mutual coupling of the local surface plasmon (LSP) in the gap between the two layers of Au gratings and the surface propagating plasmon (SPP) on the surface of the Au gratings. Then, we … Web1 de set. de 2024 · Broadband reflecting mirrors with high reflectivity are crucial for constructing a VCSEL cavity with a high Q factor. High-contrast grating (HCG) made of two materials with high contrast index exhibits broadband with high reflectivity by proper design of the geometrical parameters such as the grating period, the grating thickness …

WebThe improvements due to small incision lenticule extraction (SMILE) in vision, e.g., in spherical equivalent (SE) and visual acuity (VA), has been widely recognized. However, the contrast sensitivity (CS) change after SMILE was not certain. Here, we investigated the effect of SMILE on CS before, 1 day after and 7 days after surgery and then clarified the … WebHá 1 hora · Background The differentiation of minimal-fat—or low-fat—angiomyolipomas from other renal lesions is clinically challenging in conventional computed tomography. In this work, we have assessed the potential of grating-based x-ray phase-contrast computed tomography (GBPC-CT) for visualization and quantitative differentiation of minimal-fat … Webcreation of coupled cavity systems.7 However, HCGs make use of high-index-contrast to achieve high re ectance; they are often surrounded by air and require relatively complex fabrication processes to remove the sacri cial layer under the HCG layer.1 Suspended, they are susceptible to vibrational instability,8 ine cient in heat dissipation, and ... soft tone meaning
