properties are affected only within a few nanometers from the wall surface, others are
affected over long length scales, but the range is not clear. In this work, we have examined
the dielectric response of confined water under the influence of external electric fields along
with the dipolar fluctuations at equilibrium. The confinement induces a strong anisotropic
effect which is evident up to 100 nm channel width, and may extend to macroscopic …
