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 receiving antenna.
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.
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.
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.
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.
