Chiral sculptured thin films are useful as circular-polarization filters because they display the circular Bragg phenomenon arising from the helical shape of their nanowires. These composite materials exploit the interaction of the electric/magnetic field with the strain tensor in two different classes of materials to deliver magnetoelectric coefficients that are much higher than in their natural counterparts. N2 - The fabrication of metamaterials with new, multifunctional architectures that will enable applications in sensing, security, transportation and other areas is discussed. The homogeneity of HCM is a consequence of the electromagnetic wavelengths being much larger than the inclusion dimensions.", Researchers have been predicting the effective constitutive properties of a homogenized composite materials (HCM). Magnetoelectric composite materials develop a magnetization in response to the application of an electric field, and a polarization in response to a magnetic field. Abstract = "The fabrication of metamaterials with new, multifunctional architectures that will enable applications in sensing, security, transportation and other areas is discussed.
