How do nanostructures keep plastics transparent while improving toughness and light control? PMMA, polycarbonate, COC ...

PMMA, polymethyl-methacrylate, is a thermoplastic acrylic linear polymer, the mer of which is illustrated in the diagram. PMMA is transparent, with a refractive index of 1.49, and easily formed into ...

Metamaterials are artificial structures that have been engineered to offer unconventional properties not found in the natural world. Over the past decade, there has been considerable investigation ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...
