Graphite refractive index
WebThe relative static permittivity, εr, can be measured for static electric fieldsas follows: first the capacitanceof a test capacitor, C0, is measured with vacuum between its plates. Then, using the same capacitor and … Webthe graphene/graphite refractive index, n g = n − iκ,which is itself a function of the thickness d due to the different bandstructure versus graphene layer number. For oblique incidence, the full anisotropy of the refractive index must be taken into account. Similar calculations can be performed for transmission reflection and contrast. 3.2 ...
