Chapter 32. Finite Difference Time Domain: A Case Study Using FPGAs
Wang Chen, Miriam LeeserDepartment of Electrical and Computer Engineering Northeastern University
This chapter presents a reconfigurable hardware accelerator that implements the FDTD method. We first present background, including applications of the FDTD method. We then provide analysis and design details of the FPGA accelerator for FDTD.
The FDTD Method
Modeling electromagnetic behavior has become a requirement for key technologies such as cellular phones, mobile computing, lasers, and photonic circuits. The finite-difference time-domain (FDTD) method, which provides a direct, time domain solution to Maxwell’s equations in differential form with relatively good accuracy and flexibility, ...
