Thanks for your comment. The simulation of conformal metasurfaces requires a lot of memory cost. So, by my current system I cannot simulate them because the whole structure should be drawn (the regular periodic boundary conditions cannot be used). If I find an simple example of it I will try to provide the tutorial.
What results? Only the design method is explained in the video not simulation! If you mean the design example, please watch the video again accurately, you'll find the mistake in your calculation.
