摘　　要：利用有限元分析软件COMSOL Multiphysics仿真了馈口位置、样品大小、样品位置和多馈口激励对微波加热效率的影响,并与文献报道的实验结果进行了比较。研究表明,馈口位置、样品大小和样品位置对微波吸收效率有较大的影响;多馈口激励时微波加热的均匀性得到了改善。Based on the commercial software COMSOL Multiphysics, microwave power efficiency is investigated, as a function of the structure and position of feed port(s), and the size and position of the samples in the applied field, and results from the simulation are compared to the current literature. The study shows that feed port position, and sample size and position have considerable influence on the microwave power efficiency, and that multi-port feeding increases the temperature-uniformity of exposed samples.
