Comprehensive Electromagnetic Analysis Software
FEKO is a comprehensive computational electromagnetics (CEM) code used widely in the telecommunications, automobile, space and defense industries. FEKO offers several EM field solvers under a single licence. Hybridization of these techniques enables the efficient analysis of a very broad spectrum of EM problems. These include the analysis of antennas, microstrip circuits and biomedical systems, the placement of antennas on electrically large structures, the calculation of scattering as well as the investigation of electromagnetic compatibility (EMC). With the MLFMM, and the true hybridization of the solvers, FEKO is considered the global market leader for antenna placement analysis.

Asymptotic methods are the preferred method for calculating the radar cross section (RCS) of targets like aircrafts since the main parts of the target are more than an order of magnitude larger than the wavelength. However, an engine inlet with fan blades will need a more rigorous calculation method, such as the multi-level fast multipole method (MLFMM). This presents the challenge of combining a rigorous method with asymptotic methods to compute the RCS of an aircraft with engine inlets.
The Internet of Things (IoT) is a gateway to understanding how to communicate with technology, and how technology can provide more in depth information about everything. It is an umbrella for many wireless technologies, covers a broad set of applications, and is targeted to specific vertical markets. Many developers are now creating IoT products using Altair’s electromagnetic simulation tools and system level modeling solutions. This article discusses the three waves predicted for the development of connected devices, and how Altair is positioned to help growth in this industry.
This article presents their process of using FEKO software in conjunction with optimizing and validating sensor designs in order to fast-track readiness for aircraft safety and commercial applications.
A single-beam substrate antenna is simply comprised of a slot coupled microstrip antenna with a large lens that is constructed on top of it. In 2001, scientists had proposed designs for both the single and multi-beam mmWave circulary polarized substrate lens antennas. This white paper takes these designs and demonstrates creating them through FEKO modeling.
Driving aid radar systems are critical to enabling key technologies in the development of autonomous vehicles. With the need to meet not only road safety applications, but parking assist functions as well, certain specifications must be maintained for the antenna to be integrated into the vehicle.
A printed reflectarray is a high-gain, low profile, low-cost antenna that combines the advantages of parabolic reflector antennas with microstrip arrays. This white paper demonstrates how to easily create a printed reflectarray and its simpler feeds through the use of FEKO simulation software.
To answer the universe’s most profound questions, 11 countries have joined together in an effort to create the Square Kilometer Array (SKA) radio telescope project. The SKA will be a large collection of antennas that will be spread over large distances to work together as an interferometric array. When completed, the SKA will be 10,000 times faster and 50 times more sensitive than any existing radio telescope. This article explains how FEKO simulation is used to study the antenna interference characteristics in detail and in such a short amount of time.
This white paper explains how to compute cross-coupling effects between a cable bundle and 3G antenna mounted on a vehicle through the utilization of the cable modeling interface in FEKO. It also demonstrates the FEKO GUI elements that are useful for setting up an investigation into the cross-coupling between transmitters and cable bundles.
When using bundles of electrical cables in vehicles, aircrafts, ships, and buildings, electrical designers are met with the challenges of electromagnetic compatibility and interference. The long cables are more prone to radiate or pick up irradiation than many other electrical components and systems. This white paper discusses how these challenges may be met through the aid of FEKO’s electromagnetic simulation capabilities.
A slotted waveguide array is a popular choice for use in radar systems with its mechanical robustness, compactness, and ability to handle high power levels. This array is modeled in Altair’s FEKO software in order to determine radiation patterns and array efficiency. The white paper shows the slotted waveguide array in use, and presents graphs and images of its different patterns, measurements, and efficiencies.
