Metamaterial analog of electromagnetically induced transparency

Phys Rev Lett. 2008 Dec 19;101(25):253903. doi: 10.1103/PhysRevLett.101.253903. Epub 2008 Dec 19.

Abstract

We demonstrate a classical analog of electromagnetically induced transparency in a planar metamaterial. We show that pulses propagating through such metamaterials experience considerable delay. The thickness of the structure along the direction of wave propagation is much smaller than the wavelength, which allows successive stacking of multiple metamaterial slabs leading to increased transmission and bandwidth.
