One of the most fundamental concepts in our profession is impedance. Due to the nuances of the mathematics related to this quantity, the minutia of what is taking place and the associated nomenclature ...

Abstract: Instead of optimizing dimensions of an antenna, variable reactors are loaded on the antenna and the reactance values are optimized to achieve desired characteristics. The possibility of ...

The theory developed in II is extended to cover the case of a superconductor, and a formula is derived relating the r.f. resistivity to the superconducting penetration depth and other parameters of ...

Bioelectrical Impedance Analysis (BIA) is a widely adopted, non‐invasive technique used to estimate body composition by applying a low-level alternating electrical current through the body. This ...
