Iowa State, Ames Lab physicist developing, improving designer optical materials
Date:12/16/2010

r describes the development of optical metamaterials from thin films to 3-D nanostructures. They also describe the challenges of further, practical development of the new materials.

"First, the structures must be tiny and are therefore difficult and expensive to produce," Soukoulis said. "Optical metamaterials also absorb light, making it difficult to create a metamaterial superlens."

But Soukoulis and Wegener offer some hope in their paper. They say experiments have demonstrated optical metamaterials can operate within the visible light spectrum, 3-D optical metamaterials can be produced and light loss in metamaterials can be reduced.

They wrote the ideal optical metamaterial requires all three properties. Wrapping them all into one new metamaterial will take more research and development. And then, researchers will need to find ways to reduce the cost of production.

But, wrote Soukoulis and Wegener, the introduction of advanced fabrication techniques to metamaterials research "may lead to realization of such designer materials."
