| 摘 要： | 利用转移矩阵理论分析了任意折射率分布平板波导的传输特性，导出了非均匀平板波导的近似解析色散方程，并指出了ＷＫＢ近似的局限性，数值比较的结果表明，文中所得公式的精确度优于传统的ＷＫＢ方法和其它近似方法。

| Abstract: | A new method for obtaining the analytical dispersion characteristics of planarwaveguides with arbitrary refractive index profile is presented. The method is based onthe transfer matrix theory and a new interpretation of the WKB approximation isproposed. A comparison with other methods and the exact numerical results shows thatour method is much more accurate than the ordinary WKB method and other existingapproximate methods. |
