Description
Summary:Among the techniques widely used in CEM (Computational Electromagnetics), the FDTD method (Finite-Difference Time Domain) is one of the most demanding in computational resources. Despite the computing power available today on a personal computer, industry demands the analysis of large and complex models to be used in several electromagnetic applications. The algorithm of the FDTD method is based on the Yee cell. The Yee cell is a space-time discretization of Maxwell's equations. The performance of the FDTD method is limited by the bandwidth of the traditional algorithm. When describing the dynamics of Maxwell equations through slabs or spatiotemporal macro-cells larger than the Yee cell, the re-use of calculated fields is increased. In consequence, the performance of traditional FDTD algorithm is also increased.
