WebLet us start with the calculation of the static dielectric properties. The most convenient way to determine the Born effective charges, dielectric-, piezoelectric tensors is by means of density functional perturbation theory ( LEPSILON = .TRUE. ). ISMEAR = 0 SIGMA = 0.01 EDIFF = 1.E-8 ## to get the Born effective charges ## and the macroscopic ... Web23. aug 2013 · The spatial refractive index distribution used for the simulations of the bent fibers corresponds to the effective relative dielectric constant of Equation (1). In Figure 1c , we can see the first resonant coupling by plotting the modal index deviation, δn m , with respect the fundamental mode index at κ = 0, λ = 1,550 nm, as a function of ...
