The half-wave plate need not be fixed with respect to the polarizing filter.
For the garnets used, the peak RF power level is inversely proportional to the saturation magnetization, and the length of the ferrite half-wave plate also is inversely proportional to the saturation magnetization.
The ferrite half-wave plate uses a quadrupole field geometry [8] that must be rotated to effect phase shift.
