Abstract
A synthesis method based on a recurrent circling search algorithm is proposed for obtaining a very low loss normal-incidence broadband visible (vis) or near-infrared (NIR) antireflection (AR) coating design. Its design algorithm is quite simple and straight, and a fairly high resultant AR performance can also be achieved. It is shown that the mean residual reflectance of a broadband vis AR coating design in the range of 400–750 nm and a broadband NIR AR coating design in the range of 800–1600 nm, obtained by the recurrent circling search method using a two-material system, can be reduced to below 0.035 and 0.063%, respectively.
