Invisibility Cloaks to Become DIY?

Facebook X LinkedIn Email
DURHAM, N.C., May 7, 2013 — Invisibility cloaks, first demonstrated in complex lab experiments at Duke University seven years ago, could become much simpler to create using 3-D printing, a Duke engineer believes. "I would argue that essentially anyone who can spend a couple thousand dollars on a nonindustry-grade 3-D printer can literally make a plastic cloak overnight," said Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke's Pratt School of Engineering. Duke's Yaroslav Urzhumov holds the Frisbee-like invisibility cloak prototype created using a 3-D printer....Read full article

    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
