Determination of three-dimensional structure in photon scanning tunnelling microscopy

Abstract
We present an analytic solution to the problem of determining three-dimensional object structure, described by the spatial dependence of the susceptibility, from data accessible through photon scanning tunnelling microscopy (PSTM) experiments. An analysis is presented of the scattering of evanescent waves with detection of the scattered field by a probe in the near zone of the scatterer. The results provide tomographic imaging capability in PSTM.
