Example Model

An MRI birdcage model is used as an example to demonstrate the application macro that plots multiple S-parameter traces.

The birdcage MRI coil has two ports at the bottom rung. They are excited with equal magnitudes and 90° phase difference. Both rungs have sixteen equal-value capacitors, which tune the resonance of the system. The diameter of the coil is 30 cm. Around the coil is a cylindrical shield. The birdcage coil is aligned with the Z axis.
