A general approach based on the discrete system analysis was developed for analyzing the stability behavior of the time-domain finite element methods (TDFEM). The approach included time-domain finite element modeling of dispersive media, time-domain finite element-boundary integral (FE-BI) method, high-order time-domain finite element schemes and orthogonal time-domain finite element method. The stability criteria for the scheme employing newly developed 3-D orthogonal vector bases was calcultaed in terms of the time step. Results showed that the time step should be less than 0.12 ns in order to gaurantee stability.
