Group velocity of the acoustic eigen-modes in sonic crystals
Zhen Ye
In this brief report, the group velocity of the eigen-modes in sonic crystals is derived, and shown to equal the averaged energy velocity of the eigen-modes. How the group velocity…
Acoustic scattering by periodic arrays of air-bubbles
Zhen Ye
This paper considers acoustic scattering by and propagation through line and plane arrays of air-bubbles in liquid media. The self-consistent method is used to derive the effective…
About negative refraction and left handed materials
Zhen Ye
Here I present an overview of recent studies of the phenomenon of negative refraction and left-handed materials. I will discuss some basic questions pertinent to the problem. It is…
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…
Band gap or negative refraction effects?
C. -H. Kuo, Z. Ye
By a rigorous numerical simulation based on the standard multiple scattering theory, we investigate the optical transmission in photonic crystal structures, formed by dielectric cy…
