Optical transmission of photonic crystal structures formed by dielectric cylinders: evidence for non-negative
1Wave Phenomena Laboratory, Department of Physics, National Central University, Chungli, Taiwan, Republic of China.
Abstract:
By a rigorous numerical simulation based on the standard multiple scattering theory, we investigate optical transmission in photonic crystal structures, formed from dielectric cylinders embedded in parallel in a uniform medium. In contrast to previous conjectures, the results indicate that the imaging effect of a flat photonic crystal slab, which has been interpreted as a signature of negative refractive effects, is caused by a tunneling or self-guiding effect in the presence of partial band gaps.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
