Microwave heating of electrically conductive materials

In recent years, considerable interest has been drawn to microwave heating of powder metals and other electrically conductive materials. In this paper, we consider absorption of electromagnetic waves in materials with different effective conductivities for different microwave heating conditions. Specific features of microwave heating at the maxima of electric and magnetic fields in a standing-wave applicator are discussed. Absorption in materials containing conductive particles with dielectric shells are studied in detail using the effective-medium approximation.
