This article presents a hybrid modeling approach for coaxial transmission line antenna feeders, focusing on the impact of common-mode currents on the antenna radiation pattern. By explicitly modeling the outer shield of coaxial cables, we can accurately predict and mitigate RF interference, enhancing antenna system performance for RF engineers and enthusiasts.

In this article, we dive deep into near-field calculations to establish RF exclusion zones. By understanding near-field and far-field regions, occupational vs. public exposure, health impacts, and practical methods, we ensure compliance with EMF guidelines and safeguard human health.

Traditional coil inductance calculations often rely on simplified approximations. AN-SOF offers a more accurate approach by considering factors like non-uniform magnetic fields, conductor losses, and complex coil geometries. By using AN-SOF, you can obtain precise inductance values, visualize magnetic field and current distributions, to improve your coil designs.
