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.
This script illustrates how the INIRC 88 safety standards and NRPB 89 safety standards are added as a dataset that allows
you to plot the threshold values on a graph.
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.
Note: The session, radiation_zones.pfs, is included in the Feko installation.
The session contains the results from the antenna simulation and the following three
scripts:
INIRC88
This script generates a near field result that incorporates the
calculated near fields and the INIRC 88 safety standards for
occupational limits.
NRPB89
This script generates a near field result that incorporates the
calculated near fields and the NRPB 89 safety standards.
standards
This is a custom dataset that contains both the INIRC 88 and
NRPB 89 safety standards. The result shows the maximum field
limits for both magnetic and electric fields over the calculated
frequency band.
View the electric and magnetic field limits for the INIRC 88 and NRPB 89 safety
standards over the frequency band.
Determine if the point (-0.0316, -0.067, -0.2) m is within the safety
limits.
Note: The electric field exceeds the maximum limit over the bandwidth of 1.031 –
1.179 GHz.
