Altair Engineering Altair Engineering Inc. is an American multinational information technology company headquartered in Troy, Michigan. It provides software and cloud solutions for simulation, IoT, high performance computing (HPC), data analytics, and artific ...

. The name is derived from the German acronym "Feldberechnung für Körper mit beliebiger Oberfläche", which can be translated as "field calculations involving bodies of arbitrary shape". It is a general purpose 3D electromagnetic (EM) simulator. FEKO originated in 1991 from research activities of Dr.

University of Stuttgart The University of Stuttgart (german: Universität Stuttgart) is a leading research university located in Stuttgart, Germany. It was founded in 1829 and is organized into 10 faculties. It is one of the oldest technical universities in Germany wit ...

, Germany. Cooperation between Dr. Jakobus and EM Software & Systems (EMSS) resulted in the commercialisation of FEKO in 1997. In June 2014,

acquired 100% of EMSS-S.A. and its international distributor offices in the United States, Germany and China, leading to the addition of FEKO to the

Altair Altair is the brightest star in the constellation of Aquila and the twelfth-brightest star in the night sky. It has the Bayer designation Alpha Aquilae, which is Latinised from α Aquilae and abbreviated Alpha Aql ...

Hyperworks suite of engineering simulation software. The software is based on the Method of Moments (MoM) integral formulation of

Maxwell's equations Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. ...

and pioneered the commercial implementation of various hybrid methods such as: * Finite Element Method (FEM) / MoM where a FEM region is bounded with an integral equation based boundary condition to ensure full coupling between the FEM and MoM solution areas of the problem. * MoM /

Physical Optics In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid. This usage tends not to include effec ...

(PO) where computationally expensive MoM current elements are used to excite computationally inexpensive PO elements, inducing currents on the PO elements. Special features in the FEKO implementation of the MoM/PO hybrid include the analysis of dielectric or magnetically coated metallic surfaces. * MoM /

Geometrical Optics Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of ''rays''. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstan ...

Uniform Theory of Diffraction In numerical analysis, the uniform theory of diffraction (UTD) is a high-frequency method for solving electromagnetic scattering problems from electrically small discontinuities or discontinuities in more than one dimension at the same point. UTD i ...

(UTD) where computationally expensive MoM current elements are used to excite canonical UTD shapes (plates, cylinders) with ray-based principles of which the computational cost is independent of wavelength. A Finite Difference Time Domain (FDTD) solver was added in May 2014 with the release of FEKO Suite 7.0.
