For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls of water in the open ocean to ghostly ripples inside atoms. What has ...

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

Wave propagation in water waves constitutes a fundamental aspect of coastal and ocean engineering, where the interaction between incident waves and periodic structures can give rise to Bragg resonance ...

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 ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral atom in a vacuum. Now, for the first time, we have observed quantum ...

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 ...
