Image of the Week: 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. —Citlalli Sosa, CICESE Unidad Académica Monterrey, Monterrey, Mexico *Link in Bio #Surface #Plasmon #Polariton #light #polarized #laser
