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 ...

StarLab is a near-field multi-sample system with spherical geometry. Antenna radiation patterns in the far field are obtained indirectly by sampling the field near the antenna. The sampled near field ...

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

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 ...

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