Release of FEKO Suite 6.1: Feature Overview

EM Software & Systems-S.A. (Pty) Ltd is proud to announce the release of FEKO Suite 6.1. The following is a selected list of new features. FEKO users can find more detail in the FEKO Suite 6.1 download area or consult the release notes which can be found in the FEKO Suite 6.1 installation directory.

POSTFEKO views and associated Quick Report in MS Powerpoint (MS Word and PDF formats also supported)

• NGF allows for problem domain decomposition into static and dynamic parts

• Report generation in POSTFEKO: Reports can be generated in Microsoft Word, Microsoft Powerpoint and PDF formats. A quick report tool is available, as well as advanced reporting where content controls in a MS Word document can be linked to views in POSTFEKO. 
• Realised (effective) gain results readily available:  Realised (effective) gain that takes mismatch loss into account is directly available in POSTFEKO for any single source antenna model.
• Scripting post-processing of results in POSTFEKO: Advanced post-processing of results can be performed in POSTFEKO using the powerful scripting language Lua. Scripting is useful for custom post-processing, for example to calculate radiation safety zones according to a specific standard. 
• New CADFEKO interface: CADFEKO's user interface has been reworked and is now similar to the clean and simple interface of POSTFEKO. The focus is on usability with many features easily accessible from quick launch, quick access and quick tool menus, a context-based ribbon and numerous shortcut keys. 
• Numerical Green's Function Domain Decomposition:  Simulations involving some dynamic element in an otherwise static model may be greatly sped up by re-using the solution of static parts in subsequent simulations. The numerical Green's function allows for this type of domain decomposition where a problem is separated into fixed and variable parts. A typical application is the investigation into the optimal mounting position for an antenna on a large platform, such as a ship or a helicopter.

  Pre-Suite 6.1: Cuboidal mesh element VEP Post-Suite 6.1: Tetrahedral mesh element VEP

• Volume equivalence principle (VEP) for dielectrics:  The volume equivalence principle (VEP) is an extension to the Method of Moments for the modelling of dielectric objects. In Suite 6.1 tetrahedral mesh elements for the VEP are available directly in CADFEKO.

• Major extensions to integrated cable modelling: A number of extensions have been made to cable modelling in FEKO. Both irradiation (coupling of external fields into cables) and radiation are supported (excitation of cables by voltage sources).  A new combined Method of Moments and Multi-Conductor Transmission Line Theory method has been developed for cables with arbitrary current return paths. This combined MoM/MTL technique can handle gaps in conducting surfaces, but requires cables to be shielded for weak coupling to external fields.  A 2D static FEM solver to Laplace's equation that calculates cable parameters allows for the inclusion of arbitrary cable bundles.   
• Low frequency analysis: FEKO supports the analysis of very low frequency problems by using special basis functions for decomposition of the problem space. The matrix condition number for these basis functions remains low over frequency, allowing for stable low frequency solutions.
• Transmission and reflection coefficients for plane waves: Transmission and reflection coefficients for incident plane waves are available as a request in CADFEKO. The results are available in POSTFEKO for display on 2D graphs.   Transmission and reflection coefficients are often used in conjunction with periodic boundary conditions (PBC), multilayer planar Green's functions or infinite planes to calculate the properties of frequency selective surfaces (FSS) or multilayer scattering.
