损耗共面波导中瞬态信号传播特性的研究

A Study on Transient Propagation in Lossy Coplanar Waveguides

在考虑了导体和漏损耗的基础上，根据经验公式建立了瞬态信号在损耗共面波导中的传播模型，对 Ｇａｕｓｓ 和矩形脉冲的传播特性进行了研究。数值计算中，为了避免 Ｆ Ｆ Ｔ 变换的截断效应，采用了快速小波变换（ Ｆ Ｗ Ｔ），该方法加快了积分的速度。实验证明，该方法是有效的。

Propagation of Gauss and rectangular pulses along a lossy coplanar waveguide is studied in detail. Based on a new empirical formula, an efficient time domain propagation model is established, which has been applied to analyze the transient characteristics of Gauss and rectangular pulses. In order to reduce the effect of truncated FFT, the fast wavelet transform is adopted, which improves the speed of calculation. A comparison with the experimental data shows the validity of this method.
