Diffraction of electromagnetic radiation near an interface between discrete positive and negative refractive media

详细

The discrete diffraction of electromagnetic waves near the interface between two different media formed by waveguide arrays is studied. One of the arrays consists of waveguides made of a positive index material; the other, of waveguides made of a negative index material. The refraction of a beam resulting from diffraction at the interface obeys an analog of Snell’s law.
