Abstract:
A different retroreflective effect which parallels that encountered with dihedral corner reflectors is found in the scattering response of a penetrable left-handed media epsilon= mu= -1 right angle prism. More significantly, no diffraction from the vertex is found to exist and hence no field singularity for the right angle wedge. Although the results are illustrated with microwaves, the concept finds applications in optics, acoustics, elasticity, and other media characterized by negative index wave propagation.
