Researchers in Drexel University's College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

The Galaxy Express 999 runs into the darkness of space. If it were a train, you could point to the tracks it passed. But what ...

One of the physical properties of sound is its wave-like behavior. Diffraction, refraction, and interference are ...

When ocean waves reach shallow water, their complex interactions can produce lower-frequency infragravity waves. These waves ...

U.S. Navy airborne radio communications experts needed the ability for low-flying aircraft to receive and network data amid radio interference caused by ocean wave action. They found their solution ...

A theory inspired by whale tracking suggests that interference could make the peak of a light-wave packet appear to travel faster than light—without transmitting information superluminally. Whales are ...

Interference in plane-wave combinations of water waves is predicted to give rise to structures that are usually found in optical, elastic, and quantum systems. Figure 1: Water surface waves can form ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

This story was originally written for and published by Drexel News. Researchers in the College of Engineering have developed a thin film device, fabricated by spray coating, that can block ...
