Abstract

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.

微波炉物理学

这是关于微波炉物理学的两篇文章中的第一篇。本文讨论了微波在微波炉中的产生，包括谐振腔中磁控管、波导和驻波的操作。然后考虑了食物对微波的吸收，讨论了水的介电弛豫，电磁波在物质中的穿透深度，并考虑了微波加热过程中可能发生的化学变化，多光子电离或解离。

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.
