Abstract
A wire grid polarizer (WGP) can have improved performance due to a high aspect ratio (e.g. >3, >5, >10, >15, >20, or >30), where aspect ratio equals T/W, T is a sum of a thickness of wires of the first arrayplus a thickness of wires of the second array(i.e. T=Th+Th), and W is a maximum width of wires of the first arrayand/or of the second arraySuch high aspect ratio can be achieved with two arrays of wiresandeach capped by a thin filmand
