A vigorous argument has emerged on the premise that Kirchhoff’s law will fail when energy is dynamically added to the circuit. While working engineers were designing hardware for production, a large ...

A research team at Penn State has reported a significant violation of Kirchhoff’s law of thermal radiation, a principle that has been a foundation of thermal physics for 165 years. Their findings ...

A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the stage for more efficient energy harvesting, heat transfer and infrared ...
