Absorption of light by extremely shallow metallic gratings: metamaterial behavior.
Extremely shallow lamellar metallic gratings are shown to totally absorb incident light inside a wide angular interval. The full absorption still holds at the homogeneization limit when the period tends toward zero. It is shown that a lamellar grating, illuminated in normal incidence and in transerve magnetic polarization with a period lower than 1/, of the vacuum wavelength behaves like a diel...
متن کاملUltrabroadband light absorption by a sawtooth anisotropic metamaterial slab.
We present an ultrabroadband thin-film infrared absorber made of sawtoothed anisotropic metamaterial. Absorptivity of higher than 95% at normal incidence is supported in a wide range of frequencies, where the full absorption width at half-maximum is about 86%. Such property is retained well at a very wide range of incident angles too. Light of shorter wavelengths are harvested at upper parts of...
متن کاملExperimental determination of the light-trapping-induced absorption enhancement factor in DSSC photoanodes
For dye-sensitized solar cells (DSSC), the fundamental process that determines the maximum short-circuit current is the absorption of light. In such devices, this is produced by the concurrent phenomena of light absorption by dye molecules and light trapping in the mesoporous, titania photoanode structure. The decoupling of these two phenomena is important for device characterization and the de...
متن کاملEnhancement of percutaneous absorption of curcumin (turmeric pigment) by ethanol
Curcumin is the active component of Curcuma species including C. longa (turmeric). This molecule is well known for its anti-inflammatory effect, which seems to be stronger than that of hydrocortisone. Curcuma species have been used in Asian traditional medicine as topical anti-inflammatory drugs. Curcumin has poor oral bioavailability and its topical application could be of choice, particularly...
