Synopsis
Uncover how a theoretical, infinitely thin conducting helix shapes electromagnetic fields and energy flow. This rigorous study explains how a monochromatic signal interacts with a helical conductor to influence electric and magnetic fields, using vector potentials and advanced mathematical tools. The result is a detailed look at phase velocity, boundary conditions, and the surprising ways energy can radiate along and away from the helix.
This edition presents the problem setup, the methods used to evaluate key integrals, and the core conclusions about propagation constants and field behavior. It is written for readers who want a precise, model-based understanding of helix-driven electromagnetic phenomena and their implications for high-frequency devices.
- Learn the premises behind modeling a helical conductor and its field with a real propagation constant
- See how retarded vector potentials and Bessel function expansions are used to describe the fields
- Understand the conditions that lead to radiating versus non-radiating modes
- Explore how phase velocity along the helix relates to the free-space speed of light
Ideal for readers of advanced electromagnetism, applied physics, and engineering theory who seek a deep, math-grounded exploration of wave propagation on helical structures.

Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book explores electromagnetic fields induced by imposing a monochromatic excitation onto an infinitely thin helix structure. It follows other research into the nature of electromagnetic fields around helical structures, but breaks new ground by using a different approach to the problem. While previous studies approximated the helix with a cylindrical model, this book uses a retarded vector potential to account for the singular nature of an infinitely thin conductor. By defining a propagation constant, the author is able to establish the correctness of the initial assumption that an imposed electromagnetic field will induce a sinusoidal current on the helical conductor. The resulting expressions are evaluated in terms of Bessel function expansions, and the radial and axial flow of energy is analyzed, revealing that certain frequencies can induce radiating terms which cause a finite radial flow of energy. The author's approach not only advances the understanding of electromagnetic fields around helical structures, but also provides a method for extending the results to helices of finite wire diameter. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
