The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
Simple examples demonstrating using continuous frequency range, using the MLFMM for large models, using the LE-PO (large element physical optics) on subparts of the model and optimising the waveguide pin feed location.
Calculate the gain for a cylindrical horn feeding a parabolic reflector at 12.5 GHz. The reflector is electrically large (diameter of 36 wavelengths) and well separated from the horn. Several techniques available in Feko are considered to reduce the required resources for electrically large models.
Solve the horn using MLFMM and the reflector using LE-PO.

Consider the resource saving advantage of using the MLFMM for electrically large models
Create the horn and the parabolic reflector. Solve the horn using MoM and the reflector using LE-PO.
Solve the horn using MLFMM and the reflector using PO.
Create the model in CADFEKO. Define any ports and sources required for the model. Specify the operating frequency or frequency range for the model.
Define the calculation requests in CADFEKO.
Modify the model mesh in CADFEKO using the correct settings. A mesh is a discretised representation of a geometry model or mesh model used for simulation in the Solver.
Run the Solver to compute the calculation requests.
Calculate the fields of only the horn antenna. Export the fields to file for usage in an equivalent source.
Solve the horn using an equivalent near field source and the reflector using LE-PO.
Solve the horn using a spherical modes source and the reflector using LE-PO.
Compare the resource requirements and far field gain patterns for the models using different solver techniques.
Analyse the effect of the pin offset on the reflection coefficient using an optimisation grid search and the NGF solution settings.
Use characterised surfaces with ray launching geometrical optics (RL-GO) for an efficient solution of a frequency selective surface (FSS).
Simple examples demonstrating using Feko application automation, matching circuit generation with Optenni Lab and optimising a bandpass filter with HyperStudy.
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.
