For a few hours each lunar day, the radiation environment near the moon quietly shifts. Measurements now suggest that parts ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

Radiation with enough energy to cause changes at the atomic level is called ionizing radiation. It can damage cells, so it is important to measure its potential health effects – but how? Units ...

Radiation patterns for antennas can be utterly confusing, especially when presented in two dimensions, as they usually are. Fear not, [Hunter] has your back with 3D printed and color-coded radiation ...

The classic horn antenna undergoes some tough analysis and emerges with improvements that increase the frequency band to 3 GHz. The dual-ridged horn antenna (DRHA) is a workhorse in EMC and antenna ...

A two-month stint on the moon would expose astronauts to roughly the same amount of radiation as they would get living on the International Space Station for five months, according to new measurements ...

Study reveals that Melilla has lower-than-expected radiation levels, surprising scientists after 15 years of detailed analysis ...
