NASA Almond

NASA Almond 8 GHz bistatic RCS, from the JINA06 workshop. In that example a very low RCS is computed

First we create the geometry defined with parametric equations :

Create a parametric line :Geometry => Create => parametric line

and another :

Collapse the model and make a revolution to create the surface with Ox axis:

Flat the surface according to Oz axis with a scale factor 1/3 to obtain an almond.

Assign the interface properties over the surfaces, set a plane wave :

set the observation directions :

Set the frequency : 8 GHz

Save, generate the mesh and run.

The computed surface currents :

and the graph :
