A Space-Time Building Block Methodology for Time-Domain Analysis of Quasi-periodic Structures

In recent decades, time-domain (TD) numerical solvers have played an important role in the scientific community because of their capability to solve transient and broadband electromagnetic (EM) problems. To speed up the time-to-solution, those EM solvers usually make use of parallelization in the spatial domain. However, to avoid the time-sequential limitation of the TD solvers, it has been studied (S. Wang, Y. Shao and Z. Peng, “A Parallel-in-Space-and-Time Method for Transient Electromagnetic Problems,” in IEEE Transactions on Antennas and Propagation, vol. 67, no. 6, pp. 3961-3973, June 2019) the opportunity of taking advantage not only of the spatial parallelism but also of the time parallelization.
