This communication predicts an enhanced polarization phenomenon (ECP, enhanced chiral polarization) in mixtures of chiral materials. Chiral, or handed, media are of increasing interest in microwave technology these days. ECP is shown to appear for chiral inclusions of flat shape, provided that the chirality parameter of the inclusions approaches the value of the refractive index of the sample. The report also compares ECP with the dielectric anomaly, observed with metal mixtures.
