Reply To: Regarding phase-delay spectrum of metasurfaces

[Nayem Hosen]

Thank you for your response.

Actually, I am stuck with the phase delay spectrum (Figure 7b).

Also, this paper worked on the unit cell, and I got the unit cell phase plot before.

If I take the radius of 235–270 nm from the above phase graph, the figure looks like:

I don't think it is a phase delay spectrum. How can I get the exact figure 7b? Could you please give me a suggestion regarding this?
