Frequency domain vs. time domain finite element methods for calculation of fields in multimode cavities
IEEE Transactions on Magnetics(1997)
摘要
The time domain finite element method (TDFEM) is compared to the more standard frequency domain approach for calculating the electric field inside a multimode cavity loaded with a lossy dielectric. For high permittivity materials and where results at a range of frequencies are required the time domain method is found to be considerably more efficient.
