Nanoscale Devices for Rectification of High Frequency Radiation from the Infrared through the Visible: A New Approach

Figure 13

Schematic of theoretical model with protruding tip. D is the electrode separation. The arrows represent the incident and scattered waves used in the transfer-matrix simulation. The arrows in regions I and III symbolize scattering solutions, with a single incident state in region I and the corresponding reflected and transmitted states denoted by S⁻⁺ and S⁺⁺, respectively [18].
