Presentation Title Surface-charge Mobility Theory: An Explanation for Certain "Microwave Effects"
Author(s) Edward Bolling Ripley
On-Site Speaker (Planned) Edward Bolling Ripley
Abstract Scope The term "Microwave Effect" is often used to describe when something, either advantageous or deleterious occurs in a microwave field. This talk will explore surface charge mobility theory, to see how it may explain certain "microwave effects". Microwave are simply an application of electromagnetic energy, but all too often researchers simply accept the results, good or bad, without fully understanding the mechanisms involved. This talk will attempt to answer questions such as: why bulk metals don't heat in a microwave, but powdered metals do. How certain chemical reactions can occur quickly in a microwave field and with less energy input. Once the fundamentals of this theory are understood it can be used to explain a host of electromagnetic phenomena including chemical reactions, reaction kinetics, enhanced diffusion and many more. Although this talk focuses on microwaves these principals can apply to a range of electromagnetic applications.
