If this presentation is more honest than Elizabeth Holmes, yes. It has been 2 years since your comment and I haven't seen any actual demonstration of this so it is more likely Elizabeth Holmes-style BS.
We used FDTD Lumerical but can be easily done with other methods such as RCWA since unit cell for phase calculation is considered periodic arrays. For required phase calculation any ray tracing work, either write a simple code in Matlab or use ZEMAX.
The image at 5:01 to 5:03 looks a lot like a Fresnel lens. A Fresnel lens focuses a point but not a focal image. Fresnel lens causes light at the edges to take longer to intersect light from the middle because it doesn't have a thick middle part of a lens to slow that light longer.
this is a very important upcoming technology ......

Would you name or recommend any simulation tool for such meta-surfaces that can be controlled by MATLAB through an API for optimization purposes?

DAAAAAAMMMMNNNNN! This is good!

I now want to see how far away of an image it can capture set like a telescope
Darpa has a telescope demonstration: v=rpoRVtOALVg
Too much talk, not enough information. MIT has a good presentation.
Could barely understand this guy. Even the subtitles had trouble, misinterpreting many words. Work on your enunciation, dude.
