Abstract
The Cosine-shape nanostructured thin film with cosine function refractive index is fabricated by glancing angle deposition (GLAD). The angular absorbance spectrum is measured for s-polarized light in the Krestchmann configuration {prism/metal film/Cosine-shape film/air}. The electric-field distribution is analyzed at the peak in the angular absorbance spectrum. The result presents the TE mode surface plasmon wave can be excited successfully by the interface of a metal and a Cosine-shape thin film.
