Paper Abstract

We explore the effect of a newly discovered mechanism on the detection of infrared radiation using Apertureless Near Field Scanning Optical Microscopy (ANSOM). The passage of the ANSOM tip over a sample surface is modelled as a dipole moving over a halfspace. A boundary induced excitation is shown to occur, related to the retarded radiation reaction force of the dipole close to the surface. This excitation modifies the spontaneous emission characteristics of the dipole as it alters the near field. We suggest that this physical effect can cause emission at detectable levels in the infrared region thereby altering the expected signal in a typical ANSOM setup.
