STEP 1. Start newFASANT. 

STEP 2. Select File and click on New. 

STEP 3. Select Periodical Structures.

STEP 4. Select Centimeters units.

STEP 5. Click on "Cell → FSS Primitive → Disk", which requires the center and the radius, as shown in the next figure.

In this example the user enters the following values:

• Center: 0 0 0
• Radius: 0.5

STEP 6. Click on "Geometry → Point → Single point", which requires the x,y and z coordinates as shown in the next figure.

In this example the user enters the following values into the command line:

• Select point on screen [x y z]: 0 0 0.5

STEP 7. Click on "Cell → Define cell". Assign the material of the layer.

STEP 8. Click on "Simulation → Parameters". Configure the simulation with this parameters:

• Units: GHz
• Initial frequency: 10
• Final frequency: 16
• Samples: 4
• Planewave Definition: Symmetric

STEP 9. Before running the case, select "Meshing → Create Mesh".

Configure the meshing with this parameters:

• Planar surfaces: 40
• Curved surfaces: 40
• Mesh mode: Frequency, 16.0 GHz
• Processors: (Processors available)

Click on "Mesh" button launch the meshing engine as shown in the next figure:

STEP 10. Select "Calculate → Execute" and select the number of processors available.

STEP 11. When the simulation finishes we can visualizethe simulation results. Click on "Show Results → View Cuts By Frequency".

STEP 12. To view text file results, click on "Show Results → View Text Files".
