Modeling Using the Graphical User Interface
Begin by following the steps in the section “2D Modeling Using the Graphical User
Interface” on page 33 in the RF Module User’s Guide. Then continue as follows.
GEOMETRY MODELING
1 Click the Line button, and click at (0, 0.0174) and at (0, -0.0174) with the left
mouse button. Then click with the right mouse button to add the line to the
geometry.
2 Draw another line from (0.0576, 0.075) to (0.0924, 0.075).
SCALAR VARIABLES
In the Application Scalar Variables dialog box, set the frequency nu_rfwe to fq1.
BOUNDARY CONDITIONS
The default boundary condition is perfect electric conductor which is fine for all
exterior boundaries except at the ports. Interior boundaries are by default not active
meaning that the software imposes continuity.
1 From the Physics menu, open the Boundary Settings dialog box.
2 For Boundaries 1 and 7, specify the Port boundary condition with the following
settings (to set the mode specification and the mode number, go to the Port page);
when done, click OK.
SETTINGS BOUNDARY 1 BOUNDARY 7
Port number 1 2
Wave excitation at this port Selected Cleared
Mode specification Analytic Analytic
Mode number 1 1
SUBDOMAIN SETTINGS
1 From the Physics menu, choose Subdomain Settings.
