在FDTD Solutions 模拟中,频域监视器 (frequency domain monitors) 采用了时域讯号 (time domain data) 的离散傅立叶转换来计算模态。显然,我们并不想要包含初始模拟的那 部分时间讯号,因为它包含无激发模态的辐射,我们只对后部分的时间讯号有兴趣,因为这 些讯号的能量保留为共振腔的模态。您可在下页 (构建说明) ...
Figure 4. 2D FDTD simulation using the 2D effective materials gives broadband response with one simulation in the time domain. Using built-in eigenmode expansion monitors, high resolution and high accuracy broadband transmission data into an arbitrary waveguide mode can be obtained in a single simulat...
