Summary
Introduction
List of topics investigated in this chapter
The previous two chapters dealt with single- and double-interface structures composed of combinations of DPS-, ENG-, MNG- and MNG-type media that support freely propagating modes. In these chapters ϵr and μr were real positive or real negative. The topics covered in this chapter and summarized in Table 6.1 deal with a single-interface structure composed of a metallic (ENG-type) substrate having a complex ϵr and with μr = 1 and a dielectric (DPS-type) cover that can support a SP mode. The propagation constant, β, is calculated for a freely propagating mode and for a mode excited and loaded by a prism coupler using the Otto (O) and Kretschmann (K) configurations. Next, the electric and magnetic fields, local power flow, wave impedance and charge density wave at the substrate–cover interface are evaluated. Finally, the reflectivity of an incident electromagnetic wave off the base of the prism, ℛ, is calculated for both configurations. The theory of singleinterface surface plasmons was adapted from Refs. [1] to [4] and recent reviews from Refs. [5] and [6].
System
Geometry of the system
The single-interface structure considered in this chapter, shown in Fig. 6.1, consists of a thick planar metallic silver (ENG-type) substrate and a thick planar dielectric (DPS-type) cover.
