We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Ajay, 

That is correct, the FDTD is a time domain algorithm, but at the end of the simulation, the DFT monitors convert the time domain results into frequency domain results using Fourier transform, so you see the electric/magnetic field results for different wavelengths/frequencies. If you would like to see the evolution of electric field over time using a time domain monitor. Could you explain a little bit more what exactly is the metric you are looking for? You may also share a reference plot/article. Thank you!
