Coherent control of birefringence and optical activity
We show that polarization effects due to anisotropy and chirality affecting a wave propagating through a thin slab of material can be controlled by another electromagnetic wave. No nonlinearity of the metamaterial slab is ...
Coherent control of Snell’s law
We demonstrate coherent control of the generalized Snell’s law in ultrathin gradient metasurfaces constructed by an array of V-shaped slot nanoantennas.
