Energy Propagation In Dielectric And Magnetic Materials: Theoretical Notes, Definitions, And Calculations
•Full Article: Energy Propagation In Dielectric And Magnetic Materials: Theoretical Notes, Definitions, And Calculations
The following theoretical notes are based on sources such as Stratton "Electromagnetic Theory", McGraw Hill Book Company and Von Hippel "Dielectric Materials and Applications", Technology Press of M. I. T. and John Wiley and Sons.
The formulas and discussions are presented here for the convenience of the designer planning to use Dielectric Materials. Only the most practical formulas here have been selected, and an attempt has been made to simplify those presented. On the other hand, the use of many of the formulas requires the ability to manipulate complex numbers. (Emerson & Cuming, Inc. offers charts which give dielectric data on most commonly used electrical materials.)
It is important to note that the formulas presented here apply, with proper interpretations, equally well to:
1. a flat sheet in free space,
2. a slug which completely fills a section of coaxial transmission line, and
3. a rectangular solid which completely fills a rectangular wave guide operating in the TE10 mode.
