Electromagnetics Conditions

Conditions for electromagnetics physics include:
  • Circuit Port - A circuit port consists of current source along with a user-defined parallel impedance load.
  • Mode Port - Mode ports are intended for transmission lines with a disc-like surface. These represent connecting conductors across the cross-section of the end of a transmission line. The cross-section can be closed (like a coaxial cable with concentric circles) or open (like a microstrip or trace) but either case should have air or vacuum on one side.

To apply an electromagnetics condition to your model:

  • Select Electromagnetics in the ribbon of the Simulation tab and choose the condition type–either circuit port or mode port.
  • Select the first edge to create the port. As you hover over, a large yellow arrow appears. This shows the direction towards the next allowable edge.
  • Alt-select if you want to choose a different second edge.
  • Press Enter.

Impedance, magnitude and phase properties can be parameterized for Circuit Port and Mode Port. To parameterize Impedance in the physics tree, click the Add as a parameter button. A blue triangle on top implies that the value is parameterized. To parameterize Magnitude and Phase, click inside the input field and then click the Parameterize button. A highlighted parametrize button on top implies that the value is parameterized. All parameters can be viewed in the Parameters table.

Use the Size Preview option to visually review any user-defined or automatically generated local fidelities. This makes it easier to preview grid size controls before running the simulation.
