      abstract     = {A scanning tunneling microscope can be used to visualize in
                      real space effects provided by Fermi surfaces with buried
                      impurities far below substrates acting as local probes
                      [Weismann et al. Science 323, 1190 (2009)]. After scattering
                      at buried impurities, anisotropic electronic wave
                      oscillations are observed on the surface as hot spots: The
                      experiments exhibit strongly enhanced intensities in certain
                      directions and much weaker intensities in other directions.
                      A theory describing these features is developed based on the
                      stationary phase approximation for the Friedel oscillations
                      and taking into account the band structure of the host
                      material. It is demonstrated how the Fermi surface of a
                      material, for instance, through Fermi contours' critical
                      points, acts as a mirror focusing electrons that scatter at
                      hidden impurities which allow the projection of parts of the
                      Fermi surface, a quantity defined in reciprocal space, onto
                      real space.},
