什么是HFSS?
   HFSS是一种高性能的全波段的电磁仿真软件,它充分利用微软的Windows图形用户界面,可以仿真任意有体积的3D设备模型。它在一种易于学的环境中集成了仿真,可视化,建模和自动化,在这种环境中你的3D电磁问题可以很快很准确地解决。Ansoft公司的HFSS软件使用了有限元分析法,自适应网孔技术和友好的图形界面,可以使你的3D电磁问题得到很好的解决。Ansoft公司的HFSS可以用来计算各种参数,如S参数,共振频率和场参数等。它的典型应用包括以下几方面:
包模型——BGA, QFP, Flip-Chip
PCB板模型——高压面,地面,网格地,底板
硅/镓铣——螺旋感应器,变压器
EMC/EMI――屏蔽,耦合,远场近场辐射
天线/移动通信――贴片,偶极子,喇叭天线,等角单元电话天线,正方形丝状螺旋天线,SAR,无线元阵列,RCS,FSS
连接器――同轴,SFP/XFP,底板,转换器
波导――滤波器,共振器,转换器,耦合
滤波器――腔滤波器,微带,介质
    HFSS是一种交互仿真系统,它的基本网孔单元是四面体。这将允许你解决任意3D几何体,特别是那些带有复杂曲线和形状的四面体。而在一小部分时间里它可以应用其他的技术。
HFSS这个名字代表的是高频率结构仿真器。Ansoft是电磁仿真领域使用有限元分析法的先驱,它发展实现了切线向量有限元法,自适应网孔和APLS等技术。今天,HFSS继续引导着工业进行改革,像模式向网点的转换,全波段调制等。(毕业设计 )
通过从许多用户和工厂中吸收意见,Ansoft的HFSS已经改进了许多,在工业上,它是高产量研究,发展和虚拟原型的选择工具。

What is HFSS?
   HFSS is a high-performance full-wave electromagnetic(EM) field simulator for arbitrary 3D volumetric passive device modeling that takes advantage of the familiar Microsoft Windows graphical user interface. It integrates simulation,visualization, solid modeling, and automation in an easy-to-learn environment where solutions to your 3D EM problems are quickly and accurately obtained.Ansoft HFSS employs the Finite Element Method(FEM), adaptive meshing, and brilliant graphics to give you unparalleled performance and insight to all of your 3D EM problems. Ansoft HFSS can be used to calculate parameters such as SParameters, Resonant Frequency, and Fields. Typical uses include:
   Package Modeling – BGA, QFP, Flip-Chip
   PCB Board Modeling – Power/Ground planes, Mesh Grid Grounds,Backplanes
   Silicon/GaAs - Spiral Inductors, Transformers
   EMC/EMI – Shield Enclosures, Coupling, Near- or Far-Field Radiation
   Antennas/Mobile Communications – Patches, Dipoles, Horns, Conformal Cell   Phone Antennas, Quadrafilar Helix, Specific Absorption Rate(SAR),Infinite Arrays,  Radar Cross Section(RCS), Frequency Selective Surfaces(FSS)
   Connectors – Coax, SFP/XFP, Backplane, Transitions
   Waveguide – Filters, Resonators, Transitions, Couplers
   Filters – Cavity Filters, Microstrip, Dielectric
  HFSS is an interactive simulation system whose basic mesh element is a tetrahedron. This allows you to solve any arbitrary 3D geometry, especially those with complex curves and shapes, in a fraction of the time it would take using other techniques.
  The name HFSS stands for High Frequency Structure Simulator. Ansoft pioneered the use of the Finite Element Method(FEM) for EM simulation by developing/implementing technologies such as tangential vector finite elements, adaptive meshing, and Adaptive Lanczos-Pade Sweep(ALPS). Today, HFSS continues to lead the industry with innovations such as Modes-to-Nodes and Full-Wave Spice™.
  Ansoft HFSS has evolved over a period of years with input from many users and
industries. In industry, Ansoft HFSS is the tool of choice for high-productivity
research, development, and virtual prototyping.
