Standing-wave radio frequency exciter

A radio frequency (RF) exciter system for providing RF excitation to a magneto-optical defect center material comprising a plurality of magneto-optical defect centers, the RF exciter system comprising:

• a RF input;
• a controller configured to control an RF source to apply a RF signal to the RF input;
• a
• RF ground;
• and
• a microstrip line electrically connected to the RF input and short circuited to the RF ground adjacent the magneto-optical defect center material;
• wherein the controller is configured to control the RF source to apply the RF signal to the RF input such that a standing wave RF field is created in the magneto-optical defect center material.
