If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two ...

A somewhat more modest lineage of AC motors has powered most of the familiar appliances of twentieth-century life, from refrigerators to coffee grinders. Inside the Lab Index Two-phase induction motor ...

Complex light modulation—controlling light’s amplitude and phase—is key to many laser applications such as optical tweezers and holographic displays. To achieve such modulation at high ...

Scientists at the Max Planck POSTECH Center for Complex Phase Materials investigate precisely these materials. These compounds often exhibit different properties if researchers change the temperature, ...
