In this situation, multi-modes may occur in the cavity, few researchers consider the effect of high-order mode on microwave heating, and many literatures only studied the TE10 mode. By considering the high-order mode (TE20) during microwave heating, a computer model is developed to predict the time-dependent temperature distributions of matter by COMSOL Multiphysics software in this paper, and the effect of TE20 mode on the temperature predictions of matter is simulated. The temperature profile, the coefficient of variation (COV) of temperature and temperature-field of the cross-sectional are obtained in this paper. The results show that the mean temperature of the model with considering the TE20 mode is higher than that in the model without the TE20 mode after 20 seconds heating.","PeriodicalId":428997,"journal":{"name":"2019 International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123408310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
