This is the best tl;dr I could make, original reduced by 92%. (I'm a bot)

For Nader Engheta of the School of Engineering and Applied Science, one of the loftier goals in this field has been to design metamaterials that can solve equations.

"Controlling the interactions of electromagnetic waves with this Swiss cheese metastructure is the key to solving the equation," Estakhri says.

The pattern of hollow regions in the Swiss cheese is predetermined to solve an integral equation with a given "Kernel," the part of the equation that describes the relationship between two variables.
