| Abstract | ||
| Designing and modelling of photonic devices using PC simulators take a long time to get the optimum device structures. where a huge number of iterative simulations are required. So, high-speed computers are needed. A design for an FPGA-based finite difference time domain (FDTD) simulator is proposed to accelerate the simulation process where the FDTD method is a remarkably effective computational electromagnetic technique for modelling electromagnetic space. The proposed technique is tested using the analysis of two-dimensional photonic crystal bend structure. The proposed FPGA simulator is 130x faster than the MATLAB program implemented in a PC with a 2.6 GHz processor and 40G RAM. Where, the relative error between FPGA proposed simulator and the MATLAB program was 7.52%. In this study memory architecture, parallelism, pipelining and fixed-point arithmetic have been studied and optimized. Implementing this structure will significantly improve computational speed, allowing it to be used in a wide range of other computational electromagnetics domains. | ||
