New chip poised to enable handheld microwave imaging
Two versions of the letter P from the Penn logo, an example of the new microwave imaging chip's ability.

The researchers showed that the new microwave imager chip could form images of simple objects such as this metallic Penn logo. Unlike light, microwaves can travel through certain opaque objects, making microwave imagers potentially useful in a wide variety of applications. (Image: Farshid Ashtiani)

New topological insulator can reroute photonic ‘traffic’ on the fly

Penn researchers, who first discovered topological insulators in 2005, have shown, for the first time, a way for a topological insulator to make use of its entire footprint without wasted space throughout the material’s interior.
