Emss Feko v5.5
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.
The multiple solution techniques available within FEKO make it applicable to a wide range of problems for a large array of industries. Typical applications include:
* Antennas: analysis of horns, microstrip patches, wire antennas, reflector antennas, conformal antennas, broadband antennas, arrays
* Antenna placement: analysis of antenna radiation patterns, radiation hazard zones, etc. with an antenna placed on a large structure, e.g. ship, aircraft, armoured car
* EMC: analysis of diverse EMC problems including shielding effectiveness of an enclosure, cable coupling analysis in complex environments, e.g. wiring in a car, radiation hazard analysis
* Bio-electromagnetics: analysis of homogeneous or non-homogeneous bodies, SAR extraction
* RF components: analysis of waveguide structures, e.g. filter, slotted antennas, directional couplers
* 3D EM circuits: analysis of microstrip filters, couplers, inductors, etc.
* Radomes: analysis of multiple dielectric layers in a large structure
* Scattering problems: RCS analysis of large and small structures
GUI Features
* Large array of primitives for model creation (e.g. helix, cone, wire, paraboloid, hyperboloid, bezier curves)
* Importation of externally computed lists of points for creation of lines, polygons, etc.
* Tree based access to simulation elements (settings, materials, grids, results, etc.)
* Selection, zooming, 3-D mouse-only based handling, etc.
* Full solver control via GUI
Excitations
* Voltage or current source at a port
* Port definitions at wires, edges, waveguide aperture or stripline
* Plane wave
* Magnetic point source
* Electric point source
* Point source with specified radiation pattern
* Impressed line currents
* Near-field aperture
* Spherical modes
