摘要
基于积分衍射理论和相干偏振理论,研究了部分相干余弦高斯光束在左手材料中的光强的分布。研究结果表明:中心光强随工作频率增大,先增大后逐渐趋于稳定,但是随相干参量增大而减小;横向光强随相干参量增大而减小,随偏心参量增大光强的最大峰值不变,但是光强的峰值数目在不断增加。
Based on Points diffraction theory and coherent polarization theory, left-handed materials of partially co- herent cosh -Gaussian beam intensity distribution are studied. The results show that the center intensity first strengthen and then gradually smooth with increasing of the operating frequency, but it decreases with increasing of coherent param- eter. Transversal intensity decreases with increasing of coherent parameter and its maximum peak intensity is constant with increasing of centrifugal parameter, but the peak number of light intensity is increasing.
