In addition, because US-FDTD is only used in one of the subdomains, compared with global US-FDTD method, the matrix dimension of hybrid FDTD is reduced, which saves the time for eigenvalue solution.
#FDTD METHOD PROFESSIONAL#
This book is an essential guide for students, researchers, and professional engineers who want to gain a fundamental knowledge of the FDTD method. Hybrid FDTD makes the explicit time marching with a uniform time step determined by the size of coarse grid in whole domain, which reduces the iteration time. Introduction to the Finite-Difference Time-Domain (FDTD) Method for Electromagnetics provides a comprehensive tutorial of the most widely used method for solving Maxwells equations - the Finite Difference Time-Domain Method.

A compensation scheme is used on the subdomain boundary without compromising accuracy. Traditional FDTD is used in the remaining coarse grids subdomain and it is a matrix free method. US-FDTD is used in fine grids and the adjacent coarse grids subdomain and it breaks the Courant-Friedrich-Levy (CFL) condition. This hybrid FDTD method combines the superiorities of explicit unconditionally stable FDTD (US-FDTD) and traditional FDTD methods to achieve unconditional stability and high calculation efficiency. 1.1 THE FDTD METHOD The FDTD method is a numerical technique based on the nite-difference concept used to solve Maxwell’s equations for electric and magnetic eld distributions in the time and spatial domains. draw2d. Readers desiring to gain additional details about the FDTD method are referred to the literature 29 on this subject. A new hybrid Finite-Difference Time-Domain (hybrid FDTD) algorithm is proposed in this paper. Understanding the Finite-Difference Time-Domain Method (E-Book) FDTD MATLAB Files draw1d.p This function is used in one-dimensional FDTD to efficiently visualize the electric and magnetic field superimposed onto the materials across the entire grid.
