The　design　and　fabrication　of　the　micro-nanostructures　on　materials　surface　is　a　challenging　technology　which　can　modulate　and　control　the　selective　broadband　spectra　radiation,　and　the　light-matter　interaction　mechanism　behind　have　become　the　main　research　direction　of　filters,　absorbers,　heat　radiators　and　other　devices.　Due　to　its　high　carrier　mobility　and　excellent　optical　properties,　graphene　combined　with　microstructure,　is　likely　to　make　great　contributions　to　the　field　of　spectral　manipulation.　In　this　paper,　the　finite-difference　time-domain　(FDTD)　method　is　used　to　simulate　the　combination　of　graphene　and　microstructure.　Using　graphene　to　assist　silicon,　copper　and　nickel　materials　with　different　structures　by　exploring　their　spectral　selectivity　manipulation.　Regarding　the　presence　or　absence　of　graphene,　we　designed　grating　structure　model　and　pore　array　structure　model　for　these　three　materials　respectively,　and　studied　the　change　of　reflection　spectrum　by　changing　the　micro-nanostructures　parameters　of　the　model.　It　was　found　that　when　the　graphene　and　the　substrate　lattice　were　properly　matched,　the　absorption　effect　of　grating　structures　coated　with　graphene　was　stronger　than　that　of　grating　structures　without　graphene　when　the　incident　light　wavelength　in　the　range　of　300　nm-800　nm.　At　the　same　time,　it　is　confirmed　that　the　absorption　effect　of　the　grating　structure　is　better　than　that　of　the　hole　array　structure　under　the　same　incident　light　wavelength.
