.Novel characteristics of power propagation in the left-handed material fiber[J].Optoelectronics Letters,2007,3(4):257-259 Novel characteristics of power propagation in the left-handed material fiber SHENLu-fa WANGZi-hua [1]SchoolofCommunicationandInformationEngineering,ShanghaiUniversity,Shanghai200072,China [2]ScienceCollege,HuzhouTeachersCollege,Huzhou313000,China． Abstract:       In the weakly guided case, the power propagation in the core and the cladding of a left-handed material fiber is obtained by solving Maxwell's equations. The wave-guide efficiency is analyzed at cutoff and far from cutoff. Far from cutoff, the wave-guide efficiency equals to 1. At cutoff, for m=0, 1, the wave-guide efficiency equals to zero; for m=2, the wave-guide efficiency approaches to infinite; for m＞2, the wave-guide efficiency is less than zero, but its absolute value is larger than 1. Those are novel characteristics of left-handed material fiber. Hits: 3568 Download times: 182 View Full Text    Download reader
