Hi, john, Originally, FDTD method cannot set two field components into one real place strictly due to its Yee spatial structure. However, your codes may work well in a relative-high resolution condition. By the way, I don't think (amplitude (exp (* 0+1i 1.570796327))) is a good idea, because it may force MEEP running in a complex-field mode.
