The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
The example considers the transmission and reflection coefficients of a waveguide power divider.
Create the model geometry using the CAD component, CADFEKO.
See what's new in the latest release.
The example is intended for users with no or little experience with CADFEKO. It makes use of a completed rectangular horn model to familiarise yourself with model creation in CADFEKO and viewing the simulated results in POSTFEKO.
The example is intended for users with no or little experience with CADFEKO. This example is not an example intended for simulation, but rather to familiarise yourself with model creation in CADFEKO.
The example considers a left-handed circular polarised GPS patch antenna on a finite substrate.
The example considers the antenna placement of a GPS patch antenna on a quadcopter.
The example considers the coupling between a typical monopole antenna and a loaded transmission line above a ground plane.
Calculate the transmission and reflection coefficients of a waveguide power divider.
Before starting this example, check if the topics discussed in this example are relevant to the intended application and experience level.
Before starting this example, ensure that the system satisfies the minimum requirements.
There are several options available to launch CADFEKO in Microsoft Windows.
There are several options available to launch CADFEKO in Linux.
Set the model unit to millimeters.
Define variables to create a parametric model.
Create the power dividing pin using a cylinder.
Create the waveguide sections using two cuboids.
Union the geometry (Cuboid1 and Cuboid2) to create a single geometry part. A single geometry part will ensure mesh connectivity when the model is meshed.
Use the simplify tool to remove redundant faces.
Change the solid waveguide part to a shell (hollow) part with metal walls.
Create a single geometry part from the waveguide and power divider pin to ensure mesh connectivity when the model is meshed.
Voltage sources and discrete loads are applied to ports and not directly to the model geometry or mesh. A port must be defined before a source or load can be added.
Specify the frequency range of interest.
Add a near field request to calculate the fields on a surface through the centre of the waveguide.
Refine the mesh locally at the waveguide port faces. The faces for the waveguide ports require a finer mesh to represent the highest mode that should be taken into account. The higher order modes are typically evanescent modes.
Save the model to a CADFEKO.cfx file.
Launch the Solver to calculate the results. No requests were added to this model since impedance and current information are calculated automatically for all voltage and current sources in the model.
Open POSTFEKO from within CADFEKO.
This example showed the construction, configuration and solution of a waveguide power divider. The model consists of a hollow cuboidal sections with a cylinder (pin) in the centre. The near field and input reflection coefficient was calculated and displayed.
The example considers the optimisation of the gain of a bent dipole in front of a plate.
The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
Feko is a comprehensive electromagnetic solver with multiple solution methods that is used for electromagnetic field analyses involving 3D objects of arbitrary shapes.
CADFEKO is used to create and mesh the geometry or model mesh, specify the solution settings and calculation requests in a graphical environment.
POSTFEKO, the Feko post processor, is used to display the model (configuration and mesh), results on graphs and 3D views.
EDITFEKO is used to construct advanced models (both the geometry and solution requirements) using a high-level scripting language which includes loops and conditional statements.
One of the key features in Feko is that it includes a broad set of unique and hybridised solution methods. Effective use of Feko features requires an understanding of the available methods.
Feko offers state-of-the-art optimisation engines based on generic algorithm (GA) and other methods, which can be used to automatically optimise the design and determine the optimum solution.
The Feko utilities consist of PREFEKO, OPTFEKO, ADAPTFEKO, the Launcher utility, Updater and the crash reporter.
Feko writes all the results to an ASCII output file .out as well as a binary output file .bof for usage by POSTFEKO. Use the .out file to obtain additional information about the solution.
A large collection of application macros are available for CADFEKO and POSTFEKO.
CADFEKO and POSTFEKO have a powerful, fast, lightweight scripting language integrated into the application allowing you to create models, get hold of simulation results and model configuration information as well as manipulation of data and automate repetitive tasks.
Reference information is provided in the appendix.
