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.
