EMSS recently announced the release of FEKO Suite 5.5. As with every release of FEKO, this release includes significant new features in both the CAD interfaces and the solution engine. The following is a highlights list of new features on FEKO Suite 5.5. Users should visit the FEKO Suite 5.5 download area for more complete information. Users with M&S contracts automatically qualify for an upgrade to FEKO Suite 5.5 and can download the appropriate installation from this download area. Readers without M&S contracts are invited to contact their local distributor to arrange an evaluation licence.

Geometry modelling

Improvements to primitive creation

• Primitive dialogs open with sensible default values allowing easy placement of objects and a better visual indication of how a parameter affects the primitive.

Snapping

• Snapping control has been replaced with auto-snapping by snapping to special points (face centre, edge centre, etc.) close to the mouse pointer.
• Snapping also snaps to a clever dynamic grid that resizes to the most suitable size for the current view.

New align tool

• A new "align" tool has been introduced to easily place objects on structures - the align tool performs a rotation and a translation as a single transformation and translates from one workplane to another
• Ideal for citing an imported antenna model onto a platform, e.g. placing antennas imported to FEKO from Antenna Magus

User interface and usability

• EM-validation has been extended considerably and it also writes the results to a graphical log where warnings and errors are indicated and explained.
• Progress information is indicated while loading and saving of models - this is especially useful for large models.
• POSTFEKO has been extended to display axial ratio as both the minor over major axis as well as the major over minor axis.
• A new true type font (TTF) has been added to POSTFEKO to improve the display of text on 2D graphs.
• The FEM (and thus tetrahedral meshing) is now set in the same way as all the other solution methods. It is a solution method option of a dielectric region.

Windscreen antenna analysis

• Based on a MoM solution, meshing the metallic windscreen antenna elements and the car body only, not the glass
• The new technique takes into account:
  • Boundary conditions on the dielectric interfaces for multilayered glass windscreens (saves huge amount of memory compared to MoM-SEP, MoM-VEP and FEM that requires meshing of the different dielectric interfaces)
  • Coupling between closely spaced antenna elements (different to the coating method)
  • Finite-sized windscreens integrated into full car model
  • Curvature/rotation in the windscreen
