1.4.3    Drawing the structure

At this stage we will be creating the project geometry. First step that needs to be accomplished is choosing the units that will describe the geometry. To do that we go to Model tab and from Units   button we choose Millimetres. The same can be done in the Basic tab in the Circuit Settings dialogue.

The dimensions of the transmission line are as follow:

To draw the structure we go to Geometry tab. We start from drawing the transmission line inside filled with air. We need to draw only the inside of the structure (the surrounding medium is metal), thus we start from the air block, which stands for the transmission line inside. To draw the transmission line we press Create a Box  button in the Primitives section and a dialogue appears.

From the Medium combo box we choose air. Now we can proceed to setting the transmission line dimensions according to the picture above. With Position set to (0,0,0) the transmission line will be drawn so that its lower right corner is placed at this coordinates. After pressing OK button the transmission line object appears in the project.

For better visualisation of the inside of the transmission line, we change its transparency by selecting Box object on the Tree View, and changing Transparency in the View tab in Property Editor to 50.

Previous step: Defining the type of the structure and background medium.

Next step: Drawing the ports.
