of planar stratified structures involving chiral

2 6 Abstract. Behavior of different planar multilayer periodic structures due to plane wave excitation has been studied using 7 the transfer matrix method. Multilayer structure is composed of odd number of slabs and the layers at odd locations have 8 same characteristics and layers at even locations have same characteristics. For each structure, layers at odd locations are of 9 chiral nihility metamaterial whereas three different cases are considered for layers at even locations, i.e., dielectric, chiral and 10 chiral nihility. Effects of polarization rotation due to the optical activity of material's chirality is studied with respect angle 11 of incidence and frequency in THz region. Chiral nihility adds property of transparency to the structure for normal incidence. 12 Chiral nihility-chiral nihility structure for normal incidence yields transparency whereas same structure for oblique incidence 13 yields total rejection at higher frequencies. 14
