Transparent metals for ultrabroadband electromagnetic waves

Adv Mater. 2012 Apr 17;24(15):1980-6. doi: 10.1002/adma.201104483. Epub 2012 Mar 19.


Making metals transparent, which could lead to fascinating applications, has long been pursued. Here we demonstrate that with narrow slit arrays metallic plates become transparent for extremely broad bandwidths; the high transmission efficiency is insensitive to the metal thickness. This work provides a guideline to develop novel devices, including transparent conducting panels, broadband metamaterials, and antireflective solar cells.
