Creating the Model

Create the model in CADFEKO. Define any ports and sources required for the model. Specify the operating frequency or frequency range for the model.

Note: This model contains complex geometry. The creation steps are not provided, but the model is included in the Feko installation.
Note the following model details:
  • The coil has an inner radius of 15 cm and an RF shield radius of 17.54 cm.
  • The elliptical phantom has a major radius of 11 cm and a minor radius of 8.5 cm. Average head tissue properties are assigned to the phantom as follows:
    • relative permittivity: 36
    • conductivity: 0.657
  • Capacitive loads (C = 4.15 pF) are added to the wire ports between the end-ring gaps on both sides of the birdcage.
Note: This example is solved with MoM (SEP), but MoM/FEM or FDTD could also be used.
