About This Cover

20 November 2014, Volume 1, Issue 5, pp. 272-360

Scanning-electron micrograph of a metamaterial polarizer in silicon. This polarizer rotates one linear polarization by 90 degrees while the orthogonal polarization is transmitted undisturbed. Thereby, this polarizer is able to achieve a polarization conversion efficiency of ~74%. The center-to-center spacing between the squares is 400 nm.

See Menon et al., pp. 356-360.
