Surface Plasmon Polariton
A continuous spectrum laser passes through a linear polarizer to obtain p-polarized light that incides on the hyperbolic metamaterial composed of layers of titanium dioxide and gold to excite a surface plasmon polariton. This photo was taken in collaboration with Ricardo Téllez Limón.
