Some key features are:. S-Parameters Generation: Single Ended and Differential S-Parameters can be generated and plotted mixed-mode and 4 port options for differential. Dielectric Anistropy : our 2D field solver allows you to input dielectric properties in both parallel and perpendicular directions, and, additionally, calculates effective dielectric properties based on these values and the transmission line geometry.
Copper Roughness : Gauss 2D provides higher accuracy to your outputs by accounting for the copper thickness and roughness profile in your choice of Huray, Causal-Huray and Hammerstad models. Solder Mask : while many 2D field solvers are unable to account for the effects of solder mask, Gauss 2D provides a highly accurate calculation that takes solder mask thickness and dielectric properties into account by treating a conformal layer on top of the trace. Wide Array of Geometries : in FEM based field solvers, you have to build the geometry and discretize it yourself, which is a time-consuming challenge.
In our FD-based field solver, through our easy-to-use interface, you can select your geometry through a series of radio button options.
Gauss 2D allows you to solve for Microstrip, Stripline, and Coplanar waveguide geometries, and select between single ended vs differential edge-coupled , rectangular vs trapezoidal traces, isotropic vs anisotopric dielectric properties, solder mask vs embedded vs no dielectric above trace for Microstrip and CPW , open vs shielded, and symmetric vs asymmetric for Stripline configurations.
Multiconductor : in addition to the above mentioned geometric configurations, in our 2D field solver, you can simulate multiconductor transmission lines for both microstrip and stripline geometries, with all of the same configuration options, in addition to the selection of number of conductors. All Relevant Output Behavior and Properties : in addition to the effective dielectric properties as mentioned above , Gauss 2D provides all relevant insights into the electromagnetic behavior that you would hope to see from a 2D field solver of the simulated transmission line, including full RLGC not just impedance , propagation delay, and dielectric, conductor, and insertion loss.
Visualization of Electric Potential and Fields : Gauss 2D also outputs contour plots of the electric potential and electric fields in both the x and y directions. This visualization allows the user an instantaneous sanity check into the convergence of the solution and that the conducted simulation was of the intended geometric configuration. Beyond this, these plots allow the user to obtain several key insights into the behavior of the fields.
BEM-based field solvers do not output this information, due to the nature of their approximations not allowing spatial granularity, and FEM-based field solvers, even if they provide this, generally rely on the user to construct these from raw data. Easy Export of Data : Should you wish to store the data elsewhere or play around with it using an analysis tool, Gauss 2D allows for easy export to Excel or. Frequency Dependent Properties : Gauss 2D allows for extrapolation of key output properties across a broadband frequency range, inside our frequency extrapolation environment.
These data can provide deeper insights into how your transmission line would behave across the frequency spectrum and can also be exported to Excel or. Multiple Dielectrics : Gauss 2D allows you to introduce two dissimilar dielectrics both above and below the trace in addition to a solder mask or embedded configuration for microstrip or coplanar waveguide.
This allows higher flexibility in building a transmission line that accurately models your actual designs. Gauss 2D Electromagnetic Field Solver.

ANSYS Emag a self-contained electromagnetic analysis package, simulates electromagnetic fields, electrostatics, circuits, and low and high frequency current conduction.
Three types of analysis are possible:. OPERA-3d A suite of simulation tools for 3D electrostatic and magnetostatic modeling including finite element modeling tools and pre- and post-processing modules. The code is based in a Method of Moments formulation with curved segments. It is intended for solving problems in the areas of antenna analysis and design, EMC applications, transmission lines and non radiating networks. System responses can be computed in a frequency sweep and plotted in 2D and 3D graphical representations.

CSURF - a hierarchical capacitance solver for large numbers of unknowns and multiple dielectrics. The results are then directly fed into the built-in circuit simulator to get performance parameters such as delay, rise time, crosstalk, common-mode noise, and eye diagrams.
IDS S. The full three-dimensional circuit is modeled, so all interactions are automatically included in the solution. The model can be excited by numerous types of waveforms, and the transient response measured using common values such as voltage and current. Circuit parameters such as inductance, capacitance, and impedance can be derived from the transient response, and frequency-domain results such as S-parameters can also be calculated.
Far field radiation patterns can be obtained. FDTD is a full wave explicit solution of Maxwell's equations in three dimensions. In FDTD, the rectangular volume enclosing the model is discretized into a large number of small cells, which may be uniformly-sized, or may vary in size within the simulation space.
