Radio observatories like the Green Bank Telescope are in radio quiet zones that protect them from interference. NRAO/AUI/NSF, CC BY Radio telescopes are facing a problem. All satellites, whatever ...

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 ...

Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For example, when light is ...

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 ...

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...

A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to ...

Christopher Gordon De Pree has received funding from National Science Foundation. Christopher R. Anderson receives funding from the National Science Foundation, Office of Naval Research, and National ...

(THE CONVERSATION) – Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other ...
