Permittivity (sec-1) ASTM D4491 0.5 … In general, a material cannot polarize instantaneously in response to an applied field, and so the more general formulation as a function of time is That is, the polarization is a convolution of the electric field at previous times with time-dependent susceptibility given by χ(Δt). The upper limit of this integral can be extended to infinity as well if one defines χ(Δt) = 0 for Δt < 0. An instant… pilot jay
