Scientists have developed a specialised computer aided design (CAD) system for metamaterials allowing engineers to model and experiment with design.

Metamaterials are built from nanoparticles, often composite plastics and metals, and comprise extremely small, repetitive patterns. They have multiple potential uses including in electronics, insulation, heat transfer and in photovoltaics as well as acoustics and noise reduction.

Researchers from Massachusetts Institute of Technology (MIT) and the Institute of Science and Technology Austria said their technique makes it quicker and easier to model artificial metamaterials, edit their structures and simulate their properties.
