試題詳解

16. Which statement is NOT true about surface plasmon resonance?
(A) The angle at which reflectivity is at a minimum is independent of the refractive index of the dielectric.
(B) A surface plasmon is an electromagnetic wave that propagates along the boundary between a metal and a dielectric.
(C) The surface plasmon absorbs some of the incident light when it is in resonance with the incident light.
(D) A chemical-sensing layer can be added to the metal surface to create a specific response to the change in refractive index.
(E) Changes in the surface plasmon resonance angle can be measured with a precision of ~10^-4 to 10^-5 degrees.
