UT Austin Engineers Build First Nonreciprocal Acoustic Circulator: A One-Way Sound Device

A team of researchers at The University of Texas at Austin’s Cockrell School of Engineering has built the first-ever circulator for sound.

Research Helps Lay Out Theory for Metamaterials That Act as an Analog Computer

A new study by researchers at the University of Pennsylvania, The University of Texas at Austin and University of Sannio in Italy shows that metamaterials can be designed to do “photonic calculus” by working like an analog computer.

Researchers Design First Battery-Powered Invisibility Cloak

Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.

Researchers Create an Ultrathin Invisibility Cloak

Until now, the invisibility cloaks put forward by scientists have been bulky devices — an obvious flaw for those interested in Harry Potter-style applications. However, researchers at The University of Texas at Austin have developed a cloak that is just micrometers thick and can hide three-dimensional objects from microwaves in their natural environment, in all directions and from all of the observers’ positions.
