Diverse imaging of point source by a two-dimensional photonic crystal slab with square lattice is studied by the finite-difference time-domain method. Given proper frequencies, there seems to be some special directions like channels guiding the light propagation inside the photonic crystal, along wh

## Abstract Transmission spectra from equivalent negative refractive photonic crystals (PCs) composed of a triangular array of air cylinders in a GaAs matrix are studied by finite‐difference time‐domain method in the paper. Mechanism of wave resonance is probed and propagation of optical waves in t

## Abstract This paper shows that inside photonic band gap (PBG) materials the effective index of refraction __n__~__eff__~, defined in terms of group velocity, becomes negative in a certain range of frequencies. Also, near the photonic‐band edge the effective index of refraction __n__~__eff__~ att
