Diffraction grating with rectangular grooves exceeding 80% diffraction efficiency

Infrared Physics, 1993
Abstract A novel design for a surface relief grating with rectangular grooves is presented. The first reflected diffraction order shows experimentally 84% diffraction efficiency for a metallic grating. The required binary surface relief can be manufactured by using one single microlithographic fabrication step similar to standard processes in ...

High-Efficiency Diffraction in Spiders

Optical Interference Coatings, 1997
Many animals in the insect/spider world exhibit strong metallic colours [1]. Such colouration is usually called structural, because the effects are caused by diffraction of light on semi-regular structures at the scale of the wavelength. The surface of the C.

Approximate diffraction theories: efficient modeling of diffractive optical elements

Diffractive Optics and Micro-Optics, 2002
A new formulation of the generalized Kirchhoff approximation is presented which provides improved accuracy and a higher flexibility to model surface relief structures. The predicted diffraction amplitude is compared with rigorous coupled wave theory.

Diffraction edges perceived efficiency

2010
Today, noise barriers are recognized as the most effective noise minimization measures of road traffic noise near sensitive receptors located in the road surrounding areas. Especially where the urban occupation is characterized by buildings of low height. For higher buildings noise barriers can not be a completely effective solution.
