![]() Additionally, FDTD features good cache locality, which allows taking advantage of SIMD parallelization implemented in SSE and AVX instruction sets. In FDTD, the field unknowns are ordered spatially and are updated with their closest neighbors.Īs a consequence of this explicitness, the algorithm can be easily parallelized to exploit the benefits of shared- as well as distributed-memory architectures. In essence, the FDTD method is an explicit marching-on-in-time algorithm based on the staggered space-time discretization of Maxwell’s curl equations. ![]() Among the broad family of different numerical techniques found in CEM, the finite-difference time-domain (FDTD) method is one of the most widely employed, being applied in many fields, including bioelectromagnetics, photonics, electromagnetic compatibility (EMC). Computational electromagnetics (CEM) has become an essential discipline which allows the analysis of large and complex engineering problems.
