\section{intro}  Graphene has garnered a lot of interest for its unique electronic properties and its potential applications. Graphene is \\  There are two absorption properties that are involved in light-graphene interaction, interband and intraband absorption, described absorption. Described  by a  complex conductivity $\sigma=\sigma_{intra}(\omega,\mu_c,\Gamma,T)+\sigma_{inter}(\omega,\mu_c,\Gamma,T)$ [1].wefwefwfefwfwefwef
