And I can't find it on new learning forum. Could you help paste the content?@gsun FDTD Solutions为什么采用脉冲光源激励而不采用正弦波光源 86

Basically, whether you want a broadband or single-frequency result, the simulation with pulse source is much faster than using a sinusoidal wave, which will need an initial transient time, and then long steady state time in order to get the result at only a single frequency.
