The author describes the development of small-angle X-ray scattering and analyzes its advantages in the characterization of drug-delivery systems and large molecules. This article is part of a special ...

What are S-parameters? The multiple types of S-parameters beyond the small-signal variety. Using S-parameters, we can represent even the most complex RF device as a simple N-port network. Figure 1 ...

Scattering parameters (better known as s-parameters) are intrinsically a frequency-domain concept. For wireless applications, which deal with a modulated carrier wave, the frequency domain is entirely ...
