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 ...
Lunar-based measurements reveal Earth’s outgoing radiation is dominated by low-order spherical harmonics, providing unified global data for climate and environmental studies ...
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 ...
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 ...
Low-flying helicopters will be seen over downtown Washington, D.C., and the National Mall beginning on Monday to assess radiation levels in the city before the presidential inauguration on Jan. 20.
It is convenient, therefore, to start this chapter with a description of the two basic radiation patterns of sound sources. Figure 18.1a shows an ideal point source that, as a function of distance, ...
A new map offers a new perspective on the city, revealing the steady, ever-present natural radiation emerging from the ground ...
