Suppose you intend to generate surface plasmon (polariton) at the water/metal interface of water/metal/glass(prism) configuration, also known as Kretschmann configuration. Answer the following questions: (i) Why does the light irradiated to metal/glass interface need to be p-polarized? (ii) What kind of properties (e.g. thickness, electric permittivity) are required for the metal? (iii) Why does the light need to be irradiated to metal via glass
