Using the Application Macro
Execute the application macro in POSTFEKO to plot characteristic mode quantities on Cartesian graphs.
The results from a single characteristic mode analysis request will be used as input to the macro.

The Feko Getting Started Guide contains step-by-step instructions on how to get started with Feko.
The Feko Example Guide contains a collection of examples that teaches you Feko concepts and essentials.
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.
An application macro is a reference to an automation script, an icon file and associated metadata.
The application macro library allows commonly used application macros to be stored in a repository.
A collection of Lua application macros are available to automate repetitive tasks in CADFEKO.
A collection of Lua application macros are available to automate repetitive tasks in POSTFEKO.
This POSTFEKO application macro can be used to plot all the standard parameters that are available after a characteristic mode analysis simulation was performed.
Characteristic mode analysis (CMA) is the numerical calculation of a weighted set of orthogonal current modes that are supported on a conducting surface. The sets of characteristic near fields and far fields associated with these characteristic currents can provide insight into the radiating properties of structures, allowing for a systematic approach to antenna design and placement.
Characteristic mode analysis calculates various parameters of interest. The characteristic mode plotter was developed to plot these parameters, since it can be a tedious task to do this manually for multiple modes.
The characteristic mode analysis plotter application macro is used to plot the various CMA parameters for a simple dipole antenna.
Execute the application macro in POSTFEKO to plot characteristic mode quantities on Cartesian graphs.
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-processing application 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.
Plot multiport S-parameter results.
An application macro to tile any POSTFEKO views side-by-side.
This application macro uses the S-parameter data from a Feko simulation to display a coupling matrix for a multi-port scenario.
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.
A collection of smaller POSTFEKO application macro are available, but these macros do not include step-by-step instructions.
A collection of Lua macros are available to automate repetitive tasks where the workflow span both 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.
