  The energy flux patterns of inverse Goos-Hanchen (GH) shift around the
interface between air and negatively refractive photonic crystal (NRPhC) with
different surface terminations is investigated. Results show that NRPhC
exhibits inverse GH shift in TM and TE polarization, and the localization and
pattern of energy flux differ in TM and TE polarizations and are strongly
affected by surface termination. This is different to the condition of negative
permittivity materials (i.e., metal), which only presents inverse GH shift in
TM polarization. In the case of TE polarization, the energy flux pattern
exhibits the flux of backward wave whose localization changes from the surface
to inside of NRPhC with the variation of surface termination. In the case of TM
polarization, the energy flux pattern is always confined within the surface of
NRPhC, whereas its pattern changes from the flux of backward wave to vortices
at the surface of NRPhC, which is different to the energy flux of TM
polarization of metal. By properly truncating the surface of NRPhC we can
control the magnitude of inverse GH shift for TM and TE polarized light.
