Sinopsis

This significantly extended second editionáaddresses the important physical phenomenon ofáSurface Plasmon Resonance (SPR) or Surface Plasmon Polaritons (SPP) in thin metal films, a phenomenon which isáexploited in the design of a large variety of physico-chemical optical sensors. In this treatment, crucial materials aspects for design and optimization of SPR sensors are investigated and described in detail. The textácovers aáselection of nanometer thin metal films, ranging from free-electron to the platinum-type conductors, along with their combination with a large variety of dielectric substrate materials, and associated individual layer and opto-geometric arrangements. Whereas the first edition treated solely the metal-liquid interface, the SP-resonance conditions considered here are expanded to cover the metal-gas interface in the angular and wavelength interrogation modes, localized and long-range SPâÇÖs and the influence of native oxidicáad-layers in the case of non-noble metals. Furthermore,áa selection of metal grating structures that allow SP excitation is presented, as are features of radiative SPâÇÖs.áFinally, this treatise includes as-yetáhardly explored SPR features of selected metal-metal and metal-dielectric superlattices. An in-depth multilayer Fresnel evaluationáprovides the mathematical tool for this optical analysis, which otherwise reliesásolely onáexperimentally determined electro-optical materials parameters.
