Application of microwave energy for materials processing is emerging as a novel and innovative technology with many advantages over conventional processing, such as reduction in processing time resulting into energy and cost savings, providing finer microstructures, leading to improved mechanical properties and eco-friendliness etc. Microwaves are electromagnetic waves with wavelengths ranging from 1 m to 1 mm, which correspond to frequencies between 0.3 and 300 GHz. Microwave heating is a process in which the materials couple with microwaves, absorb the electromagnetic energy volumetrically and transform into heat. This is different from conventional methods where heat is transferred between objects by the mechanisms of conduction, radiation and convection. The main focus of this paper is to explain the physical origin of microwave-matter interactions.
