Abstract
We construct a negative refractive waveguide (NRW) by employing an anisotropic negative refraction index medium operated at multiple incidences and then experimentally demonstrate the slowing light effect by exciting the negative Goos-Hänchen effect originating from the fundamental degeneracy oscillatory mode within the NRW. Such experimental demonstration is further confirmed by scrutinizing the distributions of E-field and power flow in simulation. Moreover, the effective indices of the NRW are retrieved by the theoretical analysis and then are affirmed by finite element simulation. The experimental result agrees with the two simulation results well and so does the theoretical analysis. © 2013 American Institute of Physics.
