A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...
Manipulation of structured electromagnetic (EM) waves is key to boosting wireless communications capacity. Recently, scientists have invented a space-time-coding metasurface that generates structured ...
Jean-Michel Ménard, Associate Professor of Physics at the University of Ottawa and a team of researchers have paved the way for developing devices capable of upconverting electromagnetic signals to ...
NASA has launched the CANVAS CubeSat to investigate very low frequency (VLF) radio waves from lightning and human activities, tracing their path from Earth's surface into space. This mission bridges ...
Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...
As an RF component, radome design is highly dependent on materials, dimensions, and geometry, as well as other factors. We’ll ...
A South Korean research team has identified the principle behind controlling signal frequencies using 'spin waves,' which are ...

NASA launches CANVAS CubeSat to track lightning-born radio waves from Earth into space
The mission will study very low frequency waves to map impact on satellites, GPS, and space weather.
A recent article published in APL Materials defines metamaterials as artificial structures composed of subwavelength, atomic, or molecular-level components, possessing unique properties (such as ...
