Metamaterials Embedded with Geometrical Optics Could Simplify Optical Devices

Facebook Twitter LinkedIn Email Comments
3D-printed metamaterials developed by a Tufts University engineering team display properties not found in conventional materials. The fabrication methods used by the team demonstrate how stereolithography-based 3D printers can be used to create 3D optical devices through a process that fuses metamaterials with geometrical optics, or MEGO. The MEGO devices can be fabricated at a lower cost than devices made using typical fabrication methods. The researchers employed a hybrid fabrication approach that combined 3D printing, metal coating, and etching to create metamaterials with complex...Read full article
