Some examples of geometries simulated with Zephir :

![zephir_graph_f16](/images/stories/zephir/zephir_graph_f16.jpg)
F16 aircraft 1 GHz bistatic RCS. This complex structure is imported in the software from an IGES file. The electromagnetic data are entered with the user interface.
![zephir_navire](/images/stories/zephir/zephir_navire.jpg)
![zephir_navire_graph](/images/stories/zephir/zephir_navire_graph.jpg)
Boat 1 GHz bistatic RCS. The structure is placed over a perfect ground plane. The computed GO currents are visualized. The computed RCS can be directly analysed with the software.

![zephir_graph_nasa](/images/stories/zephir/zephir_graph_nasa.jpg)
NASA Almond 8 GHz bistatic RCS. In that example a very low RCS is computed. The result is compared with MoM.
