Abstract :
We have recently designed, built and measured an alternative solution to the use of classical dielectric material in anti-reflection coatings. A metal-mesh pattern has been designed to cover a frequency band greater than 90%. We discuss measurements and illustrate the extension for bi-refringent materials.
