WebConsider a long cylindrical capacitor. It consists of two concentric conducting cylinders. The space between the conductors is filled with a material having a permittivity of ϵ.The radius of the inner and outer conductors are r = r i and r = r 0 respectively. The length of the cylinders is L (assume L ≫ r o ).Assume that the total charge on the inner conductor is Q … WebAs the conductivity sigma goes to infinity, the permittivity goes to infinity. Having the Material explorer and Refractive index monitor return infinite values is not ideal, so they report the permittivity as eps = 1+ 1e6i, meaning the refractive index is reported as sqrt (1+ 1e6i)=707+707i.
