In order to be applied to electromagnetic(EM) radiation problems,a novel time-domain finite element method(TDFEM) on the basis of quadratic B-spline temporal basis functions is proposed.The formulation time-domain finite element methods is reviewed first.Then two TDFEM schemes based on quadratic B spine temporal basis functions are presented:conditional stability and unconditional stability.They are validated via canonical cases.The efficiencies of the two schemes in precision level and run time are compared.The stability analysis of the proposed formulations is summarized and then verified through numerical results.
