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 ...

In recent years, we have seen a marked increase in the demand for the construction of plants for the production of energy from renewable sources. Many efforts have been undertaken for the production ...

(Nanowerk Spotlight) When a patient receives radiation therapy for cancer treatment, doctors must carefully control the radiation dose to target tumor cells while sparing healthy tissue. This requires ...

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, ...
