W2405EP Keysight FDTD 仿真组件是以有限差分时域(FDTD)建模技术为基础开发的 Electromagnetic Professional(EMPro)仿真引擎。
FDTD 3D EM 仿真技术是基于频域的有限元法(FEM)的一个替代方案。由于 FDTD 具有简单、稳健的特性,并且能够集成各种非线性材料和器件,因此在天线设计、微波电路、生物/电磁效应、EMC/EMI 问题和光子学等广泛应用中都能发挥重要作用。
与 FEM 相比,FDTD 更适合用于比感兴趣的波长更大的结构。例如考虑到整个移动电话和人体的天线仿真,以及信号完整性应用的信道/背板仿真。关于 FEM 和 FDTD 技术相对优势的更多信息,请参阅微波工程师所使用的 EM 软件的最新技术。
W2405 Keysight FDTD 仿真器组件提供了从 EMPro 3D EM 平台运行 FDTD 仿真的能力(注意,这需要 W2401 EMPro 核心环境)。
从 EMPro 2010 开始,W2405 FDTD 仿真组件便包括标准 GPU 加速功能。利用此功能,FDTD 求解程序可以在基于 NVIDIA CUDA 的 GPU 上运行。这个 GPU 拥有数百个内核,与可能只有少量内核的 CPU 相比,可以更快完成仿真。请注意,FDTD 问题越大,所需要的内存就越大,在这些情况下,GPU 卡上需要配备大量内存(在进行 GPU 加速的 FDTD 仿真期间,仅可使用 GPU RAM,而非 CPU RAM)。
EMPro 支持基于 CUDA 的 NVIDIA GPU 硬件 (完整列表请参见 http://www.nvidia.com/object/cuda_gpus.html)。

W2408 FDTD GT 加速组件选件仍可用于提供更先进的 GPU 加速功能,支持包含色散材料的设计。
