时域有限差分法计算分析非对称共面波导色散特性
alculation and Analysis of Dispersion Characteristic of ACPW Using FDTD Method
利用FDTD方法对ACPW的色散特性进行了计算与分析，给出了计算ACPW的FDTD全空间计算模型，取高斯脉冲的激励，选择Mur二阶吸收边界条件，计算得出几种结构的ACPW的特性阻抗Z0（ω），并绘出了Z0随频率变化的曲线。计算结果与测试值取得了良好的一致性。
ispersion characteristic of asymmetrical coplanar waveguide (ACPW) using finite-difference time-domain (FDTD) method is presented, a FDTD-model of ACPW is advanced, and the transient propagating waveforms along the ACPW, which are excited by retarded Gaussian pulse, are found in the time domain. After the time-domain field distributions are obtained, frequency-domain parameters such as characteristic impedance Z0 are calculated using Fourier transformations. The results agree well with available theoretical and experimental data over a wide frequency range.
