Generally, one wants to have three to five mesh elements in the cross section of transmission lines in order to simulate impedance and current density and therefore coupling accurately. But 3D planar and fully arbitrary 3D EM simulators mesh a design structure very differently from one another see Table 1. Added material libraries and so many other features.

Most well-refined planar MoM EM simulators have thick metal modeling options available.
XFdtd: 3D Electromagnetic Simulation Software
Sonnet, in particular, is well known for extremely accurate de-embedding. Using PEC boundaries as ground planes decreases the size of the simulation mesh because that boundary metal is not getting meshed.
De-embedding can be as simple as subtracting simulatuon uniform section of transmission line from a port and may even be done at circuit simulation level outside of the actual EM simulation structure. FREE electromagnetic simulators, rather than commercial ones All full list of free computational electromagnetic code: FREE electromagnetic simulators, rather than commercial ones Here is another freeware: The dielectric layers generally extend horizontally to the end of the simulation space.
There list will e very short I guess FREE e simulators, rather than commercial ones Nice contribution, we can count on it. By comparison, planar method-of-moments MoM simulators such as Sonnet, Momentum and Axiem, use two dimensional mesh elements see Figure 4. Easy-to-use matching circuit optimization and simulatioon analysis software Optenni Lab is a professional software tool with innovative analysis features to increase the productivity of engineers requiring matching circuits.
XF's unique collection of features simplifies the analysis of even the most complex and massive problems. Workshops provide an opportunity to learn about specific applications and refresh your skills with experienced CST support staff.
Because of the generality of the formulation, fully arbitrary 3D EM simulators generally offer an eem of capabilities for dielectric anisotropy, frequency dependence and metamaterials.
Two coupled lines can have two modes. Clemson Vehicular Sjmulation Laboratory: FFmpeg -- Record, convert, and stream audio and video. Scribus -- Page layout tool. I have been in communication with Jim and others form Remcom on a daily to weekly basis for assistance in my project. Waveguide ports are the preferred choice for microstrip and stripline structures versus discrete ports. Throughout the year, CST simulation experts simu,ation eSeminars on the applications, features and usage of our software.
Instead of inserting metal ground conductors explicitly into the simulation model, one could use the PEC boundaries as ground conductors.

EMPro 3D EM Simulation Software
Fully arbitrary 3D EM simulators generally have plane wave sources and other external excitation that planar MoM EM simulators may not have. I have some mode-matching code by myself, which can solve rectangular waveguide problem, junctions and cascading. Optenni Lab offers fast fully-automatic matching circuit optimization tools, including automatic generation of multiple optimal topologies, estimation of the obtainable bandwidth of antennas and calculation of the worst-case isolation in multi-antenna systems.
Company Profile Email Us. It would be great if this post could be "sticky". MeshFix -- Lightweight mesh repair tool. The simulation of stripline, for example, has two ground planes, one above and one below a stripline center conductor.
The software and customer service are top notch!!!
