Researchers use sound waves to advance optical communication

Illinois researchers have demonstrated that sound waves can be used to produce ultraminiature optical diodes that are tiny enough to fit onto a computer chip. These devices, called optical isolators, may help solve major ...

3-D origami circuits could revolutionize electronic designs

Origami, the well-known Japanese art of paper folding, generates complex 3-D structures from flat 2-D paper. While the creation of a paper swan may be intriguing, the idea of creating 3-D circuits based on similar design ...

Protecting the power grid with circuit simulation methods

In December 2015, Russian hackers allegedly pummeled Ukraine's power grid, disrupting the flow of electricity for nearly a quarter-million Ukrainians. Then, in December 2016, roughly a year after the first attack, the hackers ...

Engineers invent method to control light propagation in waveguides

A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. ...

NASA demonstrates electronics for longer Venus surface missions

A team of scientists at NASA's Glenn Research Center in Cleveland recently completed a technology demonstration that could enable new scientific missions to the surface of Venus. The team demonstrated the first prolonged ...
