Research laboratories are constantly developing new materials that are expected to exhibit novel properties bound to revolutionize this or that technology. But it’s not enough to simply create these materials; scientists also need to find efficient methods of processing and fine-tuning them.

Moreover, composites are often made via the addition of nanoparticles into a base matrix, which is why it is necessary to find a way of manipulating the location, size, and concentration rate of these particles that would exclude even the smallest deviations that are invisible to the human eye.

Researchers from ITMO University have improved on the technique of local processing of composites based on nanoporous glass with addition of silver and copper. Now, it is possible to predict with high accuracy the optical properties of a plasmonic component during its treatment.
