De-Icing Power Transmission Wires

摘要

This report proposes a method for de-icing highvoltage electrical wires that involves exciting electromagnetic surface waves in the power line wires. It considers the issues of electromagnetic energy absorption in the controlled medium and its further conversion into heat. The report further analyzes how electromagnetic waves pass through the air-ice and the ice-conductor interfaces. The analysis covers the reflection and refraction of electromagnetic waves as affected by the electrophysical properties of air and ice, as well as by the orientation of the angles of incidence and refraction. The dielectric-conductor model is used to refine the equation that links the power carried by an electromagnetic wave to the wave properties of electromagnetic fields.
