摘要：
We investigate the guided waves in a three-layered planar waveguide, with one layer filled with air and the other two filled with the chiral nihility material. We have shown that no electric field exists in the chiral layers. However, the magnetic fields are nonzero within the chiral regions due to the decoupling between electric and magnetic fields. The disappearance of the electric field is caused by the negative reflections for two egienwaves in the chiral nihility at the boundaries of the planar waveguide. The electromagnetic energies can only be guided away from the source in the air layer. Simulation results have validated our theoretical analysis. (c) 2007 Elsevier B.V. All rights reserved.
