Analysis of Alternating Direction Implicit Multiresolution Time-Domain Method Using Daubechies' Scaling Function

摘要

The Maxwelrs equations were extended by the compactly supported wavelets' transformationIn This paper.The renewed formats of them are more succinct than conventional MRTD's equations.The numerical experiment shows that adopting the method can approach the limitation of the Nyquist's sampling theorem.The alternating direction implicit technique that is based on the compactly wavelets was usedInthe method,Based on the formula,compared with the conventional FDTD and ADI-FDTD.The results show that there are nonconditional time stability and excellent numerical dispersionInthe method.
