Print Your Own Invisibility Cloak

Duke University researchers are using 3D printers to produce working microwave cloaking materials. They suggest it’s not a difficult step to move toward printing with polymers or glass that might cloak visible light. Do-It-Yourself Invisibility with 3-D Printing – [duke.edu] Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory […]

Flexible Metamaterials

“Invisibility” cloaking devices already exist in the lab, but only with such restrictive conditions that they are not very useful. Restrictions in the range of effective optical frequencies and the size and structure of the cloaking materials leave a large gap between laboratory performance and a functional cloaking device. A new flexible form of metamaterial […]

Metamaterials

Metamaterials are artificially created materials that exhibit characteristics not found in natural materials. These unique properties are often derived from the nanoscale structure of the material instead of from the chemical makeup. Most current references to metamaterials deal with interesting electromagnetic properties and often photonics or opto-electronics. One of the most exciting applications in this […]

Naked Clothes

At MIT, a research team is developing fabric woven from light detecting fibers that are capable of capturing images. Instead of using a single lens to collect light and create an image, the web of fibers provides a distributed imaging capability across the surface of the fabric. A collection of many small data points can […]
