Waves in each region have been formulated for both normal and oblique incidences. At a given incident angle, the transmission or reflection is found to be easily adjusted to be equal to 1 for the chiral photonics using chiral nihility media. The wave tunneling and rejection properties in chiral nihility photonics, as well as their parametric dependences on periodicity, chiral nihility and incident angles, have been explicitly presented theoretically and verified numerically. 1. INTRODUCTION The rotation of the ellipse of light after passing through an isotropic chiral medium has been known [1]. In addition to those pioneering work [2–4], more recently, there is rapid development on the study of EM wave propagation in structured chiral media, e.g., chiral plate [5], Goos-H¨anchen shift on chiral-dielectric interface [6], chiral slab [7], nonspherical chiral object [8], infinite chiral and gyrotropic chiral Corresponding author: C.-W.
