Introduction
LORENTZ-HF™, the high frequency version of LORENTZ™, 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) for solving the high frequency electromagnetic fields, coupled with the ray tracing and powerful emission regime and secondary emission capabilities of LORENTZ™.
LORENTZ-HF™ 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-HF™ can also be combined with electrostatics, magnetostatics and time-domain solvers for LORENTZ-HFE™, LORENTZ-HFM™ and LORENTZ-HFTD™.
LORENTZ-LF™, the low frequency version of LORENTZ™ can be combined in a similar way for LORENTZ-LFE™ and LORENTZ-LFM™.
Features

“LORENTZ™ has very friendly user interface and the flexibility to develop CAD-like models”
Dr. Weiqiang Sun
“The best feature of LORENTZ™ is the combination of field calculation and trajectories calculation with high accuracy. It is quite convenient to check the field setting and to obtain the trajectories immediately. The calculation precision is satisfying if you make the right setting.”

“I have been using LORENTZ™ a long time now. I am very pleased with the BEM solver and trajectory analysis feature of LORENTZ™ software. The ability to solve in multiple current emission regimes is the most unique feature to allow us to create powerful solutions.”
Jim McGinn
Staff Scientist, FEI/Thermo Fisher Scientific
“LORENTZ™ is an indispensable tool for electric and magnetic field calculations. To the best of our knowledge, no other software includes the BEM solver with CAD import capability which is extremely important for our application.”
