摘要：In this paper, a detailed comparison of modal electromagnetic field distribution in two canonical microwave cavities, obtained via analytical and recently introduced numerical approaches, is presented and discussed. While the analyzed problems, namely, those of a spherical cavity and a ridged cavity are relatively simple, they still provide valuable benchmarks for novel numerical methods, allowing for early estimates of accuracy, efficiency, and convergence properties of the method. Furthermore, study of field distributions may provide useful insights about strengths and weaknesses of the approximating vector spaces which are otherwise not possible
