Presentation

The expert's tip :

This is a brief presentation of ICARE's features. Please check the examples. They provide a visual overview of what ICARE can do and how easily it can do it.

Inputs

ICARE is integrated in GiD. This easy to use and powerful CAD software provides all the features to create complex geometries. In addition, as a part of the GiD, ICARE accepts a wide range of geometry formats (GiD, I-DEAS, DXF,…). Interface for specific formats can be easily developed under query.

The electromagnetic parameters of the simulation are edited through a graphic user interface. The user can assign electromagnetic properties to each part of the geometry. He can choose a source among the following list :

Voltage sources on wires and coaxial feed
Any mode of circular, rectangular or coaxial waveguide feeds
Plane wave or source point illumination

Outputs

ICARE package allows the complete modelling of antennas, in particular :

Pre visualisation of geometries,
Post visualisation of surface currents on structures,
Near field computation and visualisation of the corresponding fields,
VSWR, input impedances and S-parameters of systems,
Far field patterns with 3D results.

ICARE is also well suited for Radar Cross Section (RCS) computations.

Methods

ICARE uses surface the EFIE / MFIE formulation and the famous method of moments (MoM) for analyzing general structures including dielectrics. Roof-top functions are used for describing geometries, which allows most flexibility for discretising surfaces. It features highly accurate matrix computation routines, which improves accuracy of obtained results on sensitive parameters such like VSWR. But it can also switch to lesser accurate computation, when speed is required. A LU out-of-core solver is used when the linear system exceeds the memory size of the computer. The parallelized version use the very portable library Scalapack.
