Caption

A pulse-modulated SPP wave moving right, guided by the interface of a dielectric material (above) and a metal (below), suddenly encounters the replacement of the dielectric material by air. Most of the energy is transmitted to the air/metal interface but some is reflected to the dielectric/metal interface. The video spans 120 femtoseconds.
