Wave Guide

open the Wave guide definition window.

A waveguide is activated if one of the check boxes (Rectangular, Circular, Coaxial) is selected. A new waveguide can be created by clicking on the « New » icon.

For the Rectangular and Circular waveguide :

• The waveguide section center corresponds to the coordinates (x, y, z) of the center of the waveguide section.

• The waveguide section first point corresponds to the coordinates (x, y, z) of the point on the wall of the waveguide in the E plane.

• The waveguide section second point corresponds to the coordinates (x, y, z) of the point on the wall of the waveguide in the H plane.

These three points define a propagation direction (the z axis in the example shown by pictures in the window). This direction must be oriented towards the waveguide inner structure.

The expert's tip :

The source position, size and orientation can (and should !) be checked using the Visualization tool.

For the coaxial waveguide, the window is slightly different :

It's the same as the rectangular and circular waveguide except for :

• The waveguide section first point corresponds to the coordinates (x, y, z) of a point on the outer wall.

• The waveguide section second point corresponds to the coordinates (x, y, z) of a point on the inner wall.

Note : Only one kind of source must be selected : Plane wave, Source Point, Radar Cross Section, Voltage Source or Wave Guide. If you select a wave guide, other selected sources will be disabled. A warning will be displayed.

The expert's tip :

A waveguide is an advanced way to feed an antenna. Check the examples section to see some applications of this feature.
