【摘要】 研究了无色散左手材料(LHM)作为芯层的对称三层平板波导中TE波的传输特性。研究表明,导波和表面波都可以在这种波导中传播。导波不存在TE0模式,只有TE0,TE1模式才会出现表面波。此外还发现在特定结构参数的波导中,可以存在同一阶模式的双传播模。详细分析了结构参数对这些特性的影响。更多还原

【Abstract】 Propagation properties of the TE mode for three slAbs waveguide with left-handed materials(LHM) as core layer were studied.The results indicate that guided and surface waves can both propagate in the waveguide system.There is no TE0 mode for guided waves.There are TE0 or TE1 mode for surface waves only.It is found that two guided wave modes with the same mode number can coexist in the waveguide with special structure parameters.The influence of structure parameter on the properties is analyzed.更多还原
