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.
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.
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.
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.

Forked Dipole Antenna (Continuous Frequency Range)
Calculate the input admittance for a simple forked dipole.
Creating the Model
Create the model in CADFEKO. Define any ports and sources required for the model. Specify the operating frequency or frequency range for the model.
Modifying the Auto-Generated Mesh
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.
