Electrical Field

Hello, I want to observe the electric field distribution on the monitor in FDTD. But the image is like frosted glass. How can I improve the quality of this image? I want to get a clean image like the 2nd picture.

    This is normal since FDTD is a discrete method.

    There are basically two methods to get smoother image:

    1: use finer mesh size. The grin spots you observed on the image is actually from the discrete mesh its self. This is the fundamental way to improve the result accuracy. You may need to increase the number of PML layers to suppress reflection.

    2: you can interpolate the result. For example using

    interp - Script command


    spline - Script command
