Performing boolean operations later onTo perform a boolean operation select the first object, choose the operation via icon or shortcut and then select one or more additional shape to process.

If two objects intersect, several boolean operations are available to produce the desired geometry and material distribution.

Sphere (new shape)

Brick (existing shape)

None The intersection is kept. The boolean operation needs to be performed later on.

None to all Same as None but no other intersection checks are performed.

Materials

PEC Perfect Electric Conductor.

Lossy Metal Highly conductive materials; considers skin depth and surface losses.

Ohmic Sheet / Tabulated Surface Impedance Definition of surface losses via complex impedance.

Normal General dielectric material. Select ε, μ and conductivity as a function of frequency with different dispersion models (Debye, Drude, Lorenz, Gyrotropic).

Anisotropic Material of type “Normal” with anisotropic properties.

Insert highlighted shape Sphere will be inserted into Brick.

Trim highlighted shape Brick will be trimmed from the Sphere.

Add both shapes Produces a single combined shape with material properties of the existing shape.

Intersect both shapes Only intersection is kept with material properties of existing shape.

Cut away highlighted shape Sphere is subtracted from brick, material properties of the brick are kept.

Special treatment of some material combinationsMetallic objects always get priority over dielectric objects if they overlap with dielectric media (no boolean operation is required in this case).

Pick Operations

Pick operations are used to select geometric entities to base various actions on them, e.g. aligning the WCS or measure distances/angles.

Picked entities can be deselected by again picking same entity.

Pick point, edge or face S

Pick characteristic point P

Pick edge center M

Pick face center A

Pick point on a circle R

Pick circle center C

Pick point on face O

Pick edge E

Pick face F

Delete picks D

Edge from coordinates

View Options Working Coordinate System (WCS)

Use the WCS to perform geometrical operations in a local coordinate system (u,v,w) independent of the global co ordinate system (x,y,z).

The following steps are required to define a WCS:

Example

1. Pick entity (see pick operations)

2. Switch on WCS

3. Align center of WCS with selected point W

4. Rotate WCS around arbitrary axis

5. Define second brick

1D / 0D Results 2D / 3D Field Monitors Y

1D Results

The most relevant 1D results are stored in the corresponding folder automatically. User defined results can be added.

Probes

The E and H fields can be recorded at specific positions inside and outside the calculation domain.

Template Based Postprocessing

Arbitrary 1D / 0D results can be extracted and post-processed automatically after each run.

Each defined 1D or 0D quantity can be used as an optimization goal.

Selected 1D graphs can be exported to e.g. Excel, MATLAB, ...

E-field H-field E-field (Farfield)

H-field (Farfield)

RCS

Time signals as well as the spectral information are stored in “1D Results”.

2D / 3D Field Monitors 1D / 0D Results Y

2D / 3D Field Monitors

Different field quantities can be recorded at a specific frequency or in a certain time frame, in 2D or 3D.

The recording of fields can be limited to a 2D plane in order to save compu-tational resources.

Time domain monitor allows the tracking of the (broadband) transient signal.

Arbitrary numbers of frequency domain monitors can be recorded in time domain simulations.

Plot Options

Frequency domain monitor

Carpet plot of E-field at a specific frequency (phase can be animated).

Time domain monitor

Carpet plot of E-field at three different time samples.

3D arrow plot Arrow plot (3D field on 2D plane)

Contour plot Contour plot (3D fields on 2D plane)

Carpet plot (3D fields on 2D plane) Isoline plot (3D fields on 2D plane)
