NUMERICAL STRIP DISTRIBUTED TRANSFER FUNCTION METHOD FOR ANALYSIS OF DIFFUSED CHANNEL WAVEGUIDES 

将数值条形传递函数方法引入了对光波导的计算.该方法将问题域划分为若干条形单元,然后建立离散模型,利用变分原理得到系统的控制方程。

Numerical strip distributed transfer function method is introduced to the analysis of diffused channel waveguides. In this method, the region is divided into strip elements, and the discrete model is built on the elements. The system equations are derived through variational principal, and solved by numerical transfer function method. Several examples are given, and compared with other methods, and the advantage of this method is described.
