FEKO

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.

    Internet of Things – Value And Waves

    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.

  • NASA Develops Wireless Sensors To Detect Lightning Strike Damage To Composite Aircrafts
    NASA Develops Wireless Sensors To Detect Lightning Strike Damage To Composite Aircrafts

    Within a typical year of operation, a transport aircraft is likely to be struck by lightning at least once or twice. Since lightning strikes are a safety hazard to aircrafts, maintenance staff must visually assess any damage to ensure safe flight operations. NASA researchers have developed a wireless sensor technology that can be applied to lightning strike protection, damage detection, and damage diagnosis on the composite materials of today’s aircrafts. 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.

  • Modeling mmWave Substrate Lens Antennas For Wireless Communications
    Modeling mmWave Substrate Lens Antennas For Wireless Communications

    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.

    Automotive Radars – Antenna Design, Integration, And Channel Modelling

    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. Radar channel interactions must also be grasped in order to have the most efficient system level design. This white paper will highlight numerous solutions that FEKO has to offer for the design and integration of automotive radars, as well as some typical design challenges, and an introduction to radar channel modelling with WinProp.

    The SKA Radio Telescope: A Global Project For A Better Understanding Of The Universe

    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.

    Cable Harness EMC/EMI: Cross Talk, Radiation, Interference And Susceptibility

    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.

  • Characteristic Mode Analysis For Antenna Placement
    Characteristic Mode Analysis For Antenna Placement

    Antenna design for high-frequency (HF) communications on a small aircraft is challenging because the antennas will always be much smaller than the wavelength. However, this disadvantage can be turned into an advantage. In the HF band the wavelengths and the aircraft size have the same order of magnitude, so through judicious antenna placement the aircraft body can be excited in such a way that the radiation pattern and the bandwidth are improved.
