Genetic Algorithms Used to Form Broadband Metamaterial

Penn State engineers have created a material that delivers custom broadband absorption that offers better protection against electromagnetic radiation over a wide range of wavelengths. The materials were created using genetic algorithms.

The team of engineers tested different metals and discovered palladium provided the best bandwidth coverage. The metamaterial is made of several palladium layers on a silicon substrate and can be easily manufactured. The final layer, a clear cap of polyimide, protects the screen and also reduces any impedance mismatch that could occur as the wave moves from the air into the material.
