Example 1

Step 1

First, start newFASANT.
Figure 1. Starting window

Step 2

Create a new newFASANT project. To do this, select the File → New option (alternatively, the press Ctrl+N).
Figure 2. File menu

Step 3

After selecting the New option, a list of the available modules is presented. The user needs to select a module from the available module list. Select MONCROS for this training example.

Step 4

Select the Geometry → Surface → Plane option.\
Figure 4. Geometry → Surface menu

Step 5

The command line panel requires some parameters at this point. Enter “-0.5 -0.5 0” as the first parameter and “1 1” as the second parameter so we create a 1x1 plane centered at the origin.

Step 6

Select the simulation parameters option.

Step 7

Select a frequency of 0.3 GHz (default options) and press Save.

Save the values for the advanced parameters of the solver.

Step 9

Select the RCS → Parameters option:

Step 11

Select Output → Observation directions.

Step 13

Before running the simulation, select the Meshing → Create Mesh option.
Figure 15. Meshing menu

Step 14

Set 10 divisions on planar and curved surfaces, set Processors to 1 and the default number of bands per octave. Press the Mesh button.
