Very interesting, that could be a game changer if it works well for camera optics.

Sorry to put a dampener on things, but I think it'll only work for specific single wavelengths - I could be wrong though!

The array of nanoantennas, dubbed a “metasurface,” can be tuned for specific wavelengths of light by simply changing the size, angle, and spacing of the antennas.
It is for a single wave length currently. I think the question is, can they be stacked for a wider range of frequencies across the visible light spectrum? Then can it be replicated and manufactured for an affordable price? However you have to start out somewhere....

Also, its made of gold. I think cameras and lenses are expensive enough as is
It is interesting, though, hope some of its ideas spill into the photography industry in a couple years.

I do not think this is relevent to camera optics.

The structure is designed to match the in-coming colour, exactly, and so could be used as a bandpass filter, so it might have applications on the sensor. It would not have the property of focal length, which is necessary for photopgraphers to frame images.

It also would not have DoF properties which make it interersting in a photographic sense for traditional DoF usages.

So: what is a 'perfect iamge'?

The amount of gold is trivial - a few dollars worth - so cost is not an issue.
