Wave propagation in self-waveguiding and negative refracting photonic crystals

摘要: 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 theory that gives account observed total internal reflection beam shifts surface compare its analogy differences with classical Goos-Hanchen shift. We also investigate phenomenon wave resonance excitation in slabs these arrays well those capable producing images through refraction when cut slab shape. A discussion is made dispersion relation waves comparison with those both metals left handed materials, its consequences for obtaining superfocusing.
