Astronomers have discovered the brightest fast radio burst ever detected and traced it to a nearby galaxy using a new network of CHIME Outrigger telescopes. The flash, nicknamed RBFLOAT, lasted only a ...
Electromagnetic radiation interferes with the operation of electronic devices and poses a threat to human health, while traditional microwave absorbing materials are difficult to meet the core ...
Abstract: Insights into stress-dependent reflection and transmission (R/T) of elastic waves are crucial for geophysical applications involving stress-dependent and angle-dependent seismic data. Stress ...
Abstract: Indoor human positioning has become crucial for applications such as health monitoring, security surveillance, human pose identification and rescue operations. However, achieving reliable ...
The ionosphere, as an essential component of the Earth’s space environment, contains free electrons that influence the amplitude and phase of radio signals. In the equatorial and low-latitude regions, ...
Researchers have developed a new system that could help improve safety of driverless cars. The system lets robots see around corners using radio waves processed by AI. Developed by Penn Engineers, the ...
