    The electromagnetic local density of states (EM-LDOS) near the surface of metal with periodic hole arrays is studied. The influences of the filling factor and the filling material in holes on the EM-LDOS are also discussed. Compared with that near the surface of the metal plate, the EM-LDOS resonance peak near the surface of metals with periodic hole arrays can split. When the filling factor increases, the resonance peak of transverse surface plasmon polaritons shifts in the low-frequency direction, while the resonance peak of longitudinal surface plasmon polaritons shifts in the high-frequency direction. When the dielectric constant of the filling material increases, both of the splitted peaks shift in the low-frequency direction, while the low-frequency peak shifts more remarkably.
