Electric field Profile

      Hello everyone,

      I would like to ask a question about a simulation I am working on in Ansys Lumerical.

      By using the Frequency-domain Profile and Power monitor, I get to measure the electric field profile of my setup. However, I do not understand why some parts of the simulated profile has such a low resolution. Is there any way I can fix this issue? As you can see in the picture, the top and the bottom portion has an especially low simulation resolution. The measure profile contains a single color.

      Thanks and please do help.

      I believe it is not resolution issue, as I can see the mesh is quite fine. The issue is to understand them:
      you are visualizing the magnitude of the field, not the real or imaginary part of the E field. Since in the transmission and reflection, the amplitude is fixed.

      The fringes shown are due to interference.

      If you visualize real part of Ex, Ey or Ez depending on your source, you will see different result:
