Product information
High Frequency Electromagnetics and Antenna Design
Altair Feko is a leading electromagnetic simulation software that uses multiple frequency and time domain techniques. True hybridization of these methods enables the efficient analysis of a broad spectrum of electromagnetic problems mainly related to antenna design and placement, scattering, radar cross section (RCS) and electromagnetic compatibility (EMC), including electromagnetic pulses (EMP), lightning effects, high intensity radiated fields (HIRF), and radiation hazard.
1. Benefits
One Product, Multiple Solvers
By offering a selection of different solvers, Feko users can choose the method that is most suitable to the problem that they are trying to solve, or use more than one solver for cross validation purposes. All Feko solvers are sold in a single bundle and are also part of the Altair HyperWorks licensing system.
True Hybridization
Feko offers industry leading hybridization of different solvers to combine the beneficial characteristics and allow more efficient and accurate analysis of multi-scale problems that are both complex and electrically large.
Solver Accuracy and Performance
Extensive validation of the numerical methods and enhancements in Feko is carried out to ensure the accuracy of our approaches.
Solver performance and parallel scaling is continually optimized to achieve leading computational efficiency.
Specialized Solutions
Altair Feko was the first to commercially offer a characteristic mode analysis (CMA) solver, which is still today the most proven and reliable. Altair Feko includes specialized solutions for bidirectional cable coupling, windscreen antennas and large finite arrays. Model decomposition workflows for classical antenna placement and EMC problems enable equivalent representation of the transmitting/receiving antennas and other devices.
