The sub-wavelength structures in moth eyes exhibit fascinating antireflective properties over the broadband wavelength region and at large incident angle by generating an air-mixed heterogeneous optical interface. In this work, antireflective behavior of transparent glass is observed with the elaborate controls of the nanopillar morphology. The reflectance spectrum shows a red shift and a notab...
-In this work, a vibrating search algorithm is applied to design a normal-incidence broadband visible antireflection (AR) coating on the flexible Polyethersulfone (PES) substrate, and then AR coats PES using ion-assisted deposition (IAD). The average visible spectral reflectivities of calculated and experimental AR performances are reduced to below 0.321 and 0.327%, respectively, revealing very...
Animals inhabiting the open ocean often conceal themselves by being highly transparent, but this transparency is compromised by light that is scattered and reflected from the body surface. New research shows that some midwater crustaceans use antireflection coatings to enhance their invisibility.
The optical properties of a commercial parylene pellicle are obtained using a classical oscillator model with a single oscillator. Using a standard design antireflection stack and beam-splitter multilayer films coated on this pellicle, its performance is greatly improved, flattening the curve and increasing its useful spectral range.
When the sunlight illuminates the front surface of solar cell, part of the incident energy reflects from the surface, and part of incident energy transmits to the inside of solar cell and converts into electrical energy. Typically, the reflectivity of bare silicon surface is quite higher; more than 30% of incident sunlight can be reflected. In order to reduce the reflection loss on the surface ...
Standing wave field distributions in three classic types of graded-index antireflection coatings are studied. These graded-index antireflection coatings are designed at wavelengths from 200 nm to 1200 nm, which is the working wavelength range of high energy laser system for inertial-fusion research. The standing wave field distributions in these coatings are obtained by the numerical calculatio...
