5G+communication simulation of ultra-high voltage field-line environment based on multi-scale DGTD algorithm
Accurate and rapid transient simulation has a significant impact on the design of antennas and equipment.This article proposes an effective domain decomposition strategy for the mixed time integration scheme of discontinuous Galerkin time-domain(DGTD)method.This strategy inherits the advantages of local implicit and local time stepping methods,and uses adjustable time scales to reduce storage and computational complexity.The numerical results demonstrate the effectiveness of the method and confirm that it can be used for fast transient simulation of complex structures in 5G advanced broadband.
