In a wave focusing device and a wave emitting device having the wave focusing device, the wave focusing device has a plurality of filters and focuses a wave by a phase overlap. The plurality of filters includes a first filter formed on a substrate, a second filter formed on the substrate and overlapping with the first filter in a first area, and a third filter formed on the substrate and overlapping with the second filter in a second area. A size of the first area is substantially same as that of the second area. A first portion of the second filter in the first area is inverted to a second portion of the second filter in the second area, with respect to a first axis. A wave passing through the wave focusing device is focused at a center of each of the first, second and third filters.

A method of manufacturing a wire grid polarizer includes: preparing a stamp having a nanostructure body at one surface and forming a mask layer with anisotropic vapor deposition at the one surface; forming a metal film on a substrate; transferring a mask layer of an upper portion of a nanostructure body in the mask layer onto the metal film; and patterning the metal film into metal lines by removing a portion that is not covered with the mask layer in the metal film with dry etching.
