Directed diffraction without negative refraction
Hung-Ta Chien, Hui-Ting Tang, Chao-Hsien Kuo +2
Using the FDTD method, we investigate the electromagnetic propagation in two-dimensional photonic crystals, formed by parallel air cylinders in a dielectric medium. The correspondi…
Guiding optical flows by photonic crystal slabs made of dielectric cylinders
Liang-Shan Chen, Chao-Hsien Kuo, Zhen Ye
We investigate the electromagnetic propagation in two-dimensional photonic crystals, formed by parallel dielectric cylinders embedded a uniform medium. The frequency band structure…
Sonic crystal lenses that obey Lensmaker's formula
Chao-Hsien Kuo, Zhen Ye
This paper presents a theoretical study of the phenomenon of acoustic imaging by sonic crystals, which are made of two-dimensional regular arrays of rigid cylinders placed in paral…
Comment on "Total Negative Refraction in Real Crystals for Ballistic Electrons and Light" (Phys. Rev. Lett. 91, 157404 (2003))
H. -F. Yau, J. -P. Liu, B. Ke +2
Recently, Zhang et al. (Phys. Rev. Lett. 91, 157404 (2003)) have demonstrated that an amphoteric refraction, i. e. both positive and negative refraction, may prevail at the interfa…
Flat lens imaging does not need negative refraction
Chao-Hsien Kuo, Zhen Ye
In a recent communication, Parimi et al. (Nature 426, 404 (2003)) reported the experimental results on imaging by a flat lens made of photonic crystals. They attributed the observe…
Light deflection by photonic crystals
Chao-Hsien Kuo, Zhen Ye
When propagating through periodically structured media, i. e. photonic crystals, optical waves will be modulated with the periodicity. As a result, the dispersion of waves will no…
