The Millimeter Wave Circuits and Antennas Lab out of the University of Arizona is working with the concept and implementation of invisibility (made possible by 3D printing, of course)!
Professor Hao Xin of UA is working with synthetic materials that are capable of reproducing the effect of super lenses (microscopes, telescopes, etc.). The invisibility aspect is described to work as a “shield” that would mask the human body from both optical and heat sensory equipment! Xin uses 3-D Printed building blocks formed with a variety of plastics, metals, and more.
No matter the material, these building blocks must possess the properties necessary to allow for their sole function: to bend energy waves. In order bend energy waves to produce the desired effect of invisibility, Xin puts into play his original mathematical sequencing of geometrical patterns. Xin designed his equations to orchestrate the desired effect of “negative refraction”; complete, utter invisibility!
Xin looks forward but not though his aspirations of one day creating the mythic- although perhaps not so- “invisibility cloak”!
