In order to simulate Graphene based patch there is requirements of many parameters in HFSS OR cst ETC. softwares.
What will be the value of conductivity is to be taken for graphene in HFSS for multilayer structure?
As electrical conductivity can be simply explained on the basis of drude model itself. Using band theory of solids, valence band and conduction band overlaps leading to have more free electrons in the conduction band. This conduction electrons are responsible for conduction, however due to so-called scattering mechanism, material possesses resistivity. Optical conductivity is rather the measure of electrical conductivity in the alternating field. Hence dielectric constant comes into play, which rules allowed propagation of light into matter. Here the term plasma frequency and relaxation time are used. Optical propagation is depend on this two important physical quantities. If the radiation is incident on matter, it drives the electron, and if there is no scattering, light gets reflected totally and hence metals are shiny. Above plasma frequency, reflection declines and transmission start to dominate. By understand this, we can simply differentiate electrical and optical conductivity. The color of the metals is also dependent on this factor
