Physics of the microwave oven

This is the first of two articles about the physics of microwave ovens. This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons, waveguides and standing waves in resonant cavities. It then considers the absorption of microwaves by foods, discussing the dielectric relaxation of water, penetration depths of electromagnetic waves in matter and, in considering the possible chemical changes during the microwave heating, multi-photon ionization or dissociation.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
