Paper Abstract

Recently the fundamentals of photonic crystal physics have experienced a revival due to investigations on new structures possessing properties such as selfwaveguiding and negative refraction. In this communication we present a theory that gives account of observed total internal reflection beam shifts on the surface of a selfwaveguiding crystal and compare its analogy and differences with the classical Goos-Hanchen shift. We also investigate the phenomenon of surface wave resonance excitation in slabs of these arrays as well as those capable of producing images through negative refraction when cut in a slab shape. A discussion is made of the dispersion relation of these surface waves on comparison with those of both metals and left handed materials, and its consequences for obtaining superfocusing.
