Simple examples demonstrating antenna synthesis and analysis.
Calculate the S-parameters (coupling) over a frequency range for three monopole antennas located near the front, middle and rear of a Rooivalk helicopter mock-up.
Calculate the coupling between a helix antenna and a Yagi-Uda antenna located in front of a large plate. Reduce computational resources by using the uniform theory of diffraction (UTD) and an ideal receiving antenna.
Calculate the coupling between two horn antennas separated by 60 wavelengths. A metallic plate between the horn antennas blocks the line-of-sight coupling. Replace the horn antennas with a far field equivalent source and ideal far field receiving antenna.
Simple examples demonstrating radar cross section (RCS) calculations of objects.
Simple examples demonstrating electromagnetic compatibility (EMC) analysis and cable coupling.
Simple examples demonstrating using waveguides and microwave circuits.
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.
Reference information is provided in the appendix.
