SCOPE

The increasing applications of microwave heating in materials processing requires the maximization of microwave absorption in materials during the heating process, which can only be achieved based on a precise characterization of associated physical properties (permittivity and/or permeability) of the irradiated targets, often dielectric materials. This course is aimed at introducing fundamentals of characterization of dielectric materials for microwave processing, with an emphasis on various techniques for characterizing the dielectric materials by measuring their permittivity (for nonmagnetic dielectrics) and permeability (for magnetodielectrics). The necessity and importance of establishing a complete database of dielectric properties of materials for microwave processing are also highlighted.

WHO ATTENDS?

Research scientists and engineers working in the area of microwave processing of materials, graduate students in physical and chemical sciences, and electronic engineering.

Attendees will learn about the underlying mechanism of microwave processing; recognize the unmet need for characterization of dielectric materials; and be able to select appropriate permittivity and permeability measurements techniques for different dielectric materials.
