A marching‐on‐in‐degree (MOD) method accelerated by graphics processing units has been developed to solve the time‐domain electric‐field integral equation for the analysis of transient electromagnetic scattering problems. With the use of weighted Laguerre polynomials as entire‐domain temporal basis functions and the Galerkin temporal testing procedure, the MOD algorithm overcomes the late‐time instability. Two matrix‐division schemes are proposed and an asynchronous approach based on streams in CUDA is adopted to accelerate the TDEFIE‐MOD algorithm. Numerical results reveal that the computational efficiency of the proposed algorithm is greatly enhanced.
