Re: [Meep-discuss] Theoretical vs Simulation not matching!

Hello, I think it is because a Gaussian function can not be properly defined in Meep. If you take a Gaussian pulse or beam and propagate it in Meep you will see that the dispersion/diffraction given by meep is not the same as that should be from theory. So this should be accounted when you add othe

Hello, I’m running into a strange problem! I hope someone can help. I have defined a chirped pulse in MEEP, and propagated it down a vacuum. On first glance, it overlays very well on the theoretical pulse (I adjusted the theory’s amplitude to match MEEPs, since I didn’t think amplitude mattered
