Electric field, local

Electric field localization to the near surface region therefore requires a large difference between lVeff and the cladding refractive index, and hence for a given waveguide core thickness the core material should have the highest possible refractive index. 

The surface plasmon oscillation can be simply visualized as a photon confined to a small particle size. These confined photons constitute an intense oscillating electric field localized on the particle surface which can be described by Equation (6) for a spherical nanoparticle which has a radius of r, dielectric function of e and distance to the molecule of d [18].

Note that the function if (g) characterizes the site neighborhood in which the meaning of the electric field is different from the applied field 8 that is, just if (g) is responsible for the electric field local heterogeneity. 

When diffusion occurs in an electrolyte solution in the absence of an external electrical field, local electrical neutrality must be maintained. When Vcj) is zero, the ionic fluxes are... 

According to the basic statement of the models we are going to summarize, the metal is conceived as a network of cations immersed in a cloud of free electrons in a crystalline structure. The transport of the ions controls the growth of the new phase (Figure 8.2). The ionic transport will depend on the nature of the system and on experimental conditions, such as temperature, local electric field, local concentration excess, etc. To better understand the continuous-film models, the main ionic transport mechanisms in crystalline solids are presented [1] as follows.
