FEKO |
|
 |
FEKO is a
comprehensive electromagnetic (EM) analysis software
suite, building on state of the art computational EM
(CEM) techniques to provide users with software that
can solve a wide range of electromagnetic problems.
|
Solver
Features
The FEKO solver is based on the Method of
Moments (MoM) and was the first commercial code
to utilise the MLFMM technique for the solution
of electrically big problems when it was
released with Suite 4.2 in June 2004.
The MoM has also been hybridized with the
following solution techniques:
* Finite Element Method (FEM)
* Physical Optics (PO)
* Geometric Optics (GO)
* Uniform Theory of Diffraction (UTD)
The hybridization implies that these solution
techniques can be applied to different parts of
the same model to optimize the solution time and
results. |
|
|
Advanced features that enable complex models to be
solved efficiently include:
* Advanced adaptive frequency interpolation scheme
for the efficient calculation of broadband
responses.
* Efficient out-of-core solver (also available in
parallel) for large scale problems.
* Multilayer planar Green's function for modelling
of real earth or dielectric substrates.
* Various options to model dielectric bodies (volume
/ surface meshes, approximations for earth, thin
sheets, coated wires).
|
|
| Applications |
| Multiple solution techniques make FEKO
applicable to a wide range of problems for a large
array of industries. Typical applications include: |
|
Antennas. Analysis of horns, microstrip patches,
wire antennas, reflector antennas, conformal
antennas, broadband antennas, arrays. |
|
Antenna placement. Analysis of antenna radiation
patterns, radiation hazard zones, etc. with an
antenna placed on a large structure, e.g. ship,
aircraft, armored car. |
|
EMC. Analysis of diverse EMC problems incl.
shielding effectiveness of an enclosure, cable
coupling analysis in complex environments, e.g.
wiring in a car, radiation hazard analysis. |
 |
Bio-electromagnetics. Analysis of homogeneous or
non-homogeneous bodies, SAR extraction. |
 |
RF components. Analysis of waveguide structures,
e.g. filter, slotted antennas, directional couplers. |
 |
3D EM circuits. Analysis of microstrip filters,
couplers, inductors, etc. |
 |
Radomes. Analysis of multiple dielectric layers in
a large structure. |
 |
Scattering problems. RCS analysis of large and
small structures. |

| Parallel Processing |
|
32-bit systems can only address 2 GBytes of RAM
per process. |
|
|
64-bit systems can address more than 2 GBytes
of RAM per process and therefore have an
advantage over 32-bit systems. |
|
|
Scalable to multiple processor servers (e.g.
SGI) or clusters with various interconnect
technologies (e.g. Ethernet, Myrinet, Infiniband). |
|
|
|
| Licencing |
|
Three licensing and price categories: Silver,
Gold and Platinum dependent on platform. |
|
Free evaluation licence. |
|
Educational licence options are available for
academic institutions or the creators of
teaching material. |
|
Classroom licences (256 MByte limitation) are
available to academic institutions who purchase
or rent full licences. |
|
FEKO LITE (Limited, licenced, but FREE version
of FEKO). |
|
Floating licences are supported via single or
redundant licence server configurations. |
|
Dongle licensing is supported for multiple
installations of a single licence. Note that
dongle licensing is only supported for Windows
and Linux on IA32, AMD64, EM64T and IA64
platforms. |
