The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
Simple examples demonstrating antenna synthesis and analysis.
Simple examples demonstrating antenna placement.
Simple examples demonstrating radar cross section (RCS) calculations of objects.
Simple examples demonstrating electromagnetic compatibility (EMC) analysis and cable coupling.
Calculate the S-parameters of a simple microstrip notch filter. Use different solvers and compare the results.
Calculate the transmission and reflection for a stepped waveguide transition from the Ku- to X-band. Use two solver methods, the method of moments (utilising waveguide ports) and the finite element method (utilising FEM modal ports).
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.
Create 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 computational electromagnetic (CEM) validate tool to perform basic validation on the CADFEKO model.
Run the Solver to compute the calculation requests.
Match the dipole using a general S-parameter network.
View and post-process the results in POSTFEKO.
Calculate the input impedance of a circularly polarised patch antenna fed through a microstrip branch coupler. Replace the branch coupler with a non-radiating network and compare with a full solution.
Calculate the S-parameters (coupling) of a four port microstrip coupler. Use the finite difference time domain method.
Simple examples demonstrating phantom and tissue exposure analsysis.
A simple example demonstrating the time analysis of an incident plane wave on an obstacle.
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.
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.
