摘要
在弱导条件下,利用Maxwell方程组,对纤芯是左手材料,包层是右手材料的光纤表面模进行了研究,得到了TE(TM)、EH和HE表面模的色散方程,.根据色散方程,画出了相应表面模和含左手材料光纤导模的色散曲线.比较这些色散曲线,发现了含左手材料光纤表面模一些新的特性.
Using Maxwell＇s equations, surface modes in a fiber with left-handed material core and right-handed material cladding under weak guidance were discussed. Some dispersion equations for TE （TM） mode, EH modes and HE modes were obtained. According to these equations, some curves for different surface modes and oscillating guided modes were plotted. These dispersion equations and curves are compared with each other. Many novel characteristics of surface modes for LHM fiber were obtained.
