摘要

用网络法结合改进的EDC近似研究了矩形截面弯曲介质波导的场分布。结果表明，磁场最大值有向外移动的趋势。还绘制了波导内外空间区域的场廓线。数值分析结果与实验结果吻合较好，与WKB方法相比，该方法更简单、方便。

A simple and effective method to analyze field distribution in curved dielectric waveguides

Field distributions of a curved dielectric waveguide with rectangular cross-section are investigated by a network method combined with a modified EDC approximation. It is shown that the field maximum tends to outwardly shift. Field profiles in the inner and outer space regions of the waveguide are also drawn. Results of numerical analysis show very good agreement with experimental results while the present approach is simpler and more convenient compared with those applying the WKB method.
