FEKO, part of Altair’s HyperWorks® suite is a comprehensive electromagnetic simulation software tool, based on state of the art computational electromagnetics (CEM) techniques, enabling users to solve a wide range of electromagnetic problems. FEKO’s multiple solution techniques make it applicable to a wide range of problems for a large array of industries. Typical applications include analyses of horns, radiation patterns & hazard zones, wire, reflector, conformal, and broadband antennas, microstrip patches, arrays, antenna placement & design. Analyses related to EMC (including shielding & cable coupling), RCS (scattering problems), waveguide structures (RF components), SAR extraction (Bio-electromagnetics), and multiple dielectric layers (Radomes)
Altair is focused on the development and broad application of simulation technology to synthesize and optimize designs, processes and decisions for improved business performance. Privately held with more than 2,300 employees, Altair is headquartered in Troy, Michigan, USA and operates more than 40 offices throughout 22 countries. Today, Altair serves more than 5,000 corporate clients across broad industry segments.
The popular FEKO Student Competition is once again open to all under-graduates and post-graduates who work on a supervised project in electromagnetic engineering and make use of FEKO. This annual competition is an opportunity for students to showcase their work.Download
In this paper the authors investigate and present a patent pending novel micro-strip coupler structure that exhibits very low RF insertion loss (high coupling) while insuring high electrical isolation (>10kV) between the wireless Network Interface Card (NIC) RF connection and the external antenna.Download
Microstrip filters, planar antennas and other RF structures are solved efficiently using the planar Green's function. Only the stripline or antenna needs to be discretised with this method. Ground planes are treated implicitly by the formulation and do not add to the number of unknowns.Download
Antennas are increasingly incorporated into the windscreens of automobiles. FEKO has a special formulation to design the antenna and calculate the effect of the vehicle on the radiation pattern of the antenna.Download
The combination of the integral equation (MoM) and the differential equation (FEM) solvers allows the efficient solution of real world radiation hazard problems e.g. calculating the effect of an antenna's radiation on humans sitting inside a vehicle. SAR is calculated according to international standards.Download
The combined MoM and the Multi-conductor Transmission Line (MTL) theory enables the analysis of coupling into and radiation from cable harnesses in their real-world environments.Download
Several extensions and special solvers are used in FEKO for efficient EMC analysis, e.g. adaptive frequency interpolation, cable harness analysis, SAR calculation, low frequency stabilisation, time domain analysis. Applications include shielding and coupling investigations, reverberation chamber design and EMC test environment modelling.Download
Offering both a MoM and a FEM solver FEKO is well-suited for the full-wave analysis of waveguide structures e.g. Magic-T coupler, slotted waveguide antenna, cavity- and waveguide filters. Port modes are specified or calculated and near-fields and S-parameters are extracted with ease.Download
A case study, showing the design of an array antenna for the proximity fuse of an air defence missile, is performed to illustrate the combined use of Antenna Magus and FEKO.
