Perturbative approach for diffraction due to a periodically corrugated boundary between vacuum and a negative phase-velocity material
Using a perturbative approach, we study the changes that the transformation of a refracting medium from positive/negative phase velocity to negative/positive phase velocity has on the diffraction of a plane wave due to a periodically corrugated boundary. In contrast to specular reflection, we find t...
