| 本讲座主要介绍ANSYS HFSS软件中的三种求解器：有限元法、积分方程法、和时域方法，其中积分方程法中又包括矩量法、快速多极子算法和物理光学法。上述方法有各自的特点和适用场合，这对于仿真时的选择比较重要。最后会介绍一下混合算法，混合算法在解决一些既有复杂结构又是电大尺寸的问题非常有用。 |
|
| Three types of solvers in ANSYS HFSS will be introduced in this seminar, including FEM, IE and DGTD. In IE solver three methods: MoM, FMM and PO will also be explained. These solvers have their own characters and fit for different problems. So it is important to know about some details of them. At last we will show hybrid method to solve electronic large scale problems together with complex structure. |

| 随着天线阵列规模逐渐增大，阵列天线的设计和仿真难度仍然比较大，对于阵列天线的设计，首先要解决的就是天线阵列与馈电网络的问题，需考虑馈线网络中的端口反射以及非线性器件的影响。如何使用全新的HFSS 3D layout实现复杂馈电网格设计，同时使用3D layout建模与HFSS三维建模究竟有何不同？应选择全模型的实体建模与仿真，亦或是天线阵列模块、馈电网络模块、场路协同的电路求解等模块化的建模与仿真是设计师需考虑的问题。 |
|
| 本专题主要突出HFSS 3D layout对于天线阵列中馈线网络建模与仿真功能，调用phi mesh，更快速的进行初始网络划分。同时有限大阵区域分解功能可有效解决超大型天线阵列的仿真设计工作。 |
|
| With the increase in the size of the antenna array, the difficulty in array antenna design and simulation concentrate on the interaction between antenna array and feed network. For example it should consider the feeding network port smatch / reflection and nonlinear device effects. Moreover, what’s the difference between HFSS 3D CAD and 3D layout? How to use HFSS 3D layout to design complex feed network with embedded circuit? Whether to choose full modeling HFSS 3D simulation of the whole system, alternatively, choosing modular design, such as antenna array module, feed network modules, co-simulation between “field & circuits” will be first concern of many antenna and RF circuit designers should consider. |
|
| The main highlight of this topic is HFSS 3D layout modeling and simulation for an antenna array feeding network. New technique called phi mesh, can accelerate the initial mesh process tens of times. In the meantime, very large antenna array simulation can get benefit. |

本次呈现会介绍基于ANSYS软件考虑EMI的设计流程概念。考虑EMI的设计流程是具有如下特性：
- 在设计早期洞察EMI性能
- 使用相同的仿真工具分析SI和PI
- 如果PI或SI仿真已完成，只需很少的额外时间或资源
- 完全自动化
|
|
|
This presentation introduces the concept of an EMI Aware Design Process.
The EMI Aware Design Process is a methodology that
- provides insight about the EMI performance of a device early in the design cycle
- uses the same simulation tools used for Signal and Power Integrity investigations
- requires a minimal amount of additional time and / or resources if a PI or SI simulation has been done
- is fully automated within the ANSYS tool suite
