We modified the metamaterial unit cell because a rectangular unit cell would introduce voids at the intersection of each quadrant of the cloak. Numerical simulations revealed that the performance ...

The fusion of this technology with metamaterial cloaking could enable the first visible-light cloaking device. Here's the story. Under normal circumstances, when you bombard any material with ...

This image is a Profile picture of the assembled perforated plate ground cloak. CREDIT Peter Kerrian Hanford and her team set out to engineer a metamaterial that can allow the sound waves to bend ...

Contrary to the now prevailing notion of invisibility that relies on metamaterial coatings, the scientists achieved the result using a homogenous object without any additional coating layers.

unless all you want to cloak is bananas. Stanford Assistant Professor of Materials Science and Engineering Jennifer Dionne and her co-workers have designed a new type of metamaterial with a ...

The metamaterial covered bump instead reflected light back towards the source like a flat surface would do, hiding the bump underneath. The Duke cloak does have its limitations. It only works in ...

The shaping is the key and you won’t find it in nature. That makes it a “metamaterial.” The possibility of cloaking against light waves was examined in the late 1990s as was the concept of ...

Previously, Semouchkina had designed a non-conductive glass metamaterial cloak that worked with infrared frequency waves, which are shorter than microwaves. Then, scarcely was the ink dry on their ...

Since the advent of transformation optics and subsequent initial demonstration of the microwave cloak, the field has grown rapidly. However, the complexity of the transformation optics material ...
