High frequency properties of composite membrane with in-plane aligned Sendust flake prepared by infiltration method

► Thin membranes containing in-plane aligned Sendust flakes were prepared with a novel infiltration method. ► Optimized high frequency permeability was obtained when anealing temperature is 500 °C. ► Both theoretical analysis & measurement of permittivity show that Sendust flakes have good in-plane place inside membranes.
