| 摘 要： | 采用改进后的马可梯里方法推导出了半导体超常媒质矩形波导中体模和表面模的色散方程，讨论了最低阶TM模的截止频率并画出了布里渊图。结果显示不同的波导高度具有不同的导模频带，波导高度大的对应的导模频带较宽，并且彼此之间没有重叠。除此之外，不同模式还存在着简并的趋势。最后采用作图法验证了表面模的存在性。

| Abstract: | The dispersion equations of bulk modes and surface modes in a rectangular waveguide of semiconductor metamaterial are derived by a modifiedMarcatili's method.The cutoff frequencies of the lowest TM bulk mode are discussed,and the Brillouin diagrams of different bulk modes are drawn.They demonstrate that different heights correspond to different guidance frequency ranges which have no superposition with each other and a waveguide with a larger height possesses a wider passband of light.In addition,tendencies... |
