LORENTZ-HFTM是LORENTZTM的高频版本，是一种易于使用的3D全波电磁模拟器，它基于CFIE（组合场积分方程），结合了在高频率存在下分析带电粒子轨迹的能力频率点磁场。
它使用矩量法（MoM）（或边界元法）与SINGULATM中的物理光学相结合，并与LORENTZTM的射线追踪和发射机制和二次发射能力相结合。
LORENTZ-HFTM还计算近场和远场结果、功率和方向增益、雷达截面、轴比以及输入阻抗、导纳和散射参数。
它特别适用于影响很多大功率真空电子设备设计的多核放点现象的早期仿真和解决。
LORENTZ-HFTM是LORENTZ的低频版本，可以以类似的方式组合LORENTZ-LFE和LORENTZ-LFM。
特征：
物理光学与MoM混合，以解决基本MoM或FEM无法处理的大型天线盘等问题
二次发射是可用的，发射概率取决于一次撞击能量
粒子与重力、粘度和流动性的相互作用，通过残余气体碰撞散射
来源包括：入射平面波、增量电压、线电压、波导和磁褶边
可以根据H、B、E、D、J、Z、S、Y等参数创建各种图形和绘图（近场、远场、矩形、Smith圆图、辐射图）
显示电流、场和输入阻抗的矩形图。显示功率增益和坐标图、电流和场的等高线。显示辐射方向图的3D表面图并显示S参数的Smith图
将结果导出到文本文件
参数部分允许用户自定义更改模型几何形状、材料、边界和电压条件等
LORENTZ-HFTM也可以与集成低频电或磁解算器混合，以包括以下效果：
各种排放方案，包括：Fowler-Nordheim、Child's Law、Richardson-Dushman、Schottky和Extended Schottky
模拟透镜聚焦特性、光束发射率和空间电荷
应用：
电子枪
离子枪
离子注入机
纳米管场发射器
X射线
离子推进
光斑尺寸
转向磁铁
电子显微镜
离子迁移谱
离子阱
离子质谱仪
导流板
系统要求：
64位操作系统
Microsoft Windows 10 或更高版本
安装需要大约110MB的磁盘空间
3D程序：
至少4GB的RAM运行，但对于应该使用16GB或更多RAM的较大问题，不建议这样做。使用的RAM越多，解决问题的速度就越快
强烈建议使用多核处理器，因为3D程序是多线程的
【英文介绍】
LORENTZ-HFTM, the high frequency version of LORENTZTM, is an easy-to-use 3D full-wave electromagnetic simulator based on CFIE (combined-field integral equation) combined with the ability to analyze charged particle trajectories in the presence of high frequency electromagnetic fields.
It uses the Method of Moments (MoM) (or Boundary Element Method) coupled with Physical Optics found in SINGULATMand is coupled with the ray tracing and powerful emission regime and secondary emission capabilities of LORENTZTM.
LORENTZ-HFTM also calculates near and far field results, power and directive gain, radar cross-section, axial ratio, and input impedance, admittance and scattering parameters.
It is uniquely suited for early-stage simulation and resolution of the Multipactor Discharge phenomenon affecting many high-power vacuum electronics device designs.
LORENTZ-HFTMcan also be combined with electrostatics, magnetostatics and time-domain solvers for LORENTZ-HFE, LORENTZ-HFM and LORENTZ-HFTD.
LORENTZ-LFTM, the low frequency version of LORENTZ can be combined in a similar way for LORENTZ-LFE and LORENTZ-LFM.
Features
Physical Optics hybridized into MoM to solve problems such as large antenna dishes that basic MoM or FEM cannot handle.
Full secondary emission is available with a probabilistic chance of emission depending on primary impact energies.
Particle interaction with gravity, viscosity, and mobility, scattering through residual gas collisions.
Sources include: Incident plane wave, delta voltage, line voltage, waveguide, and magnetic frill.
A wide range of graphs & plots (near field, far field, rectangular, Smith Charts, radiation patterns) can be created based on parameters such as H, B, E, D, J, Z, S, Y.
Display rectangular plots of current, fields and input impedance. Display polar plots of power gain, contours of currents and fields. Display 3D surface plots of radiation patterns and display Smith charts of s-parameters.
Export results to text files.
Powerful parametric section enables user-defined changes to model geometries, materials, boundary and voltage conditions etc.
LORENTZ-HFTM can also be hybridized with INTEGRATED low frequency electric or magnetic solvers to include effects such as:
Various emission regimes, including: Fowler-Nordheim, Child's Law, Richardson-Dushman, Schottky and Extended Schottky.
Simulate lens focusing properties, beam emittance and space charge.
