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.
This POSTFEKOapplication macro can be used to plot all the standard parameters that are available after a characteristic mode analysis simulation
was performed.
This application macro is used for calculating mean effective gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration.
The MEG ratio can also be plotted.
The Multiport post-processingapplication macro allows you to calculate results for changes in the port loading without rerunning the Solver. Results that are supported are far fields, near fields, currents and specific port parameters, for example,
the voltage, current and S-parameters of each port.
The characteristic mode synthesis and design application macro is a post-processing application macro that can be used to calculate a weighted sum for the currents, near fields, and far fields requests for specific
characteristic modes of interest. The application macro uses a modified version of the modal weighting coefficient (MWC) to use the radiating phase when synthesising
the results with the macro.
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.
This application macro is used for calculating mean effective gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration.
The MEG ratio can also be plotted.
This application macro is used for calculating mean effective
gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration. The
MEG ratio can also be plotted.
The application macro is used for calculating mean effective gain
(MEG), envelope correlation coefficient (ECC)1. Using the Maths option for the 2D graph, the MEG
ratio can also be plotted.
Currently, the application macro only supports two channel MIMO: the
two channels are simulated as two separate configurations, each with its far field
request. You can choose to sweep the cross polarization ratio (XPR), sweep the frequency
or both. The propagation environment can also be defined. The default is uniform, with .
Plots of ECC against XPR or MEG against frequency are plotted depending on the selected
options.
