FEKO by EMSS

EMSS was founded in 1994 as a company consulting in electromagnetic field analysis and antenna design. Through consulting services EMSS identified the local and international need in the aerospace, naval and automobile industries for the simulation of antennas on electrically large platforms. The commercial code FEKO (www.feko.info) was developed specifically for this market. Apart from antenna design and antenna placement EMSS has been involved in simulation of Electromagnetic (EM) fields in- and outside humans in the close vicinity of antennas.

What is 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. FEKO is based on the accurate "full wave" Method of Moments (MoM) which is fully hybridized with several other techniques including the Finite Element Method (FEM) and efficient high frequency approximation techniques (PO, GO and UTD). FEKO was also the first commercial code to offer the hugely successful Multilevel Fast Multipole Method (MLFMM). The availability of all these techniques offer a comprehensive solution for the simulation needs of the aerospace, naval, automobile and communication industries.

The combination of the MLFMM and the high frequency techniques, in particular, allow the efficient analysis of a wide range of EM problems in realistic operating environments. E.g. antenna placement on large platforms like ships or aircraft, cable coupling (EMC) analysis of complex cable bundles in vehicles and radiation hazard analysis for humans in close proximity to antennas that are mounted on large structures like mobile phone base stations. This particular ability distinguishes FEKO from the other popular EM simulation codes.
