许多作者已经对微波加热进行了模拟，通常使用基于有限元方法的商业软件。用两种不同的方法来评估电磁场分布的影响：求解麦克斯韦方程和应用朗伯定律。本文分析了圆柱形样品的尺寸对微波加热的影响，应用朗伯定律建立了一个用商业软件FEMLAB求解的数值模型，将微波吸收关系式正确地表达在圆柱形样品中。
The microwave heating has been modelled by many authors, often using commercial software based on finite element method. Two different approaches have been followed to evaluate the effects of the electromagnetic field distribution: solving the Maxwell’s equations and applying the Lambert’s law. In this paper we analyse the effect of dimensions microwave heating of cylindrical samples, developing a numerical model solved by a commercial package, FEMLAB, to simulate heat transfer in foodstuff, applying the Lambert’s law, as microwave absorption relationship correctly formulated for cylindrical geometry.
