Reply To: DGTD script error

Hi there,

Thanks for the help! 

The model works now. The online example plots the relative power and the diffraction angle. Other than that, I need to observe the phase change with the angle and the width variation of the grating. 

The research paper of this online example - 'Lin et al,. "Optical metasurfaces for high angle steering at visible wavelengths", Scientific Reports, 7, 2286 (2017)',  has plotted the 1D and 2D phase results for the different grating widths (see the attached screenshot). 

 I need to observe these data for my model as well. How to extract phase profile (1D and 2D) in DGTD?

 

Thanks!
