Abstract

The ability to create time-dependent magnetic fields of controlled\npolarization is essential for many experiments with magnetic resonance. We\ndescribe a microstrip circuit that allows us to generate strong magnetic field\nat microwave frequencies with arbitrary adjusted polarization. The circuit\nperformance is demonstrated by applying it to an optically detected magnetic\nresonance and Rabi nutation experiments in nitrogen-vacancy color centers in\ndiamond. Thanks to high efficiency of the proposed microstrip circuit and\ndegree of circular polarization of 85% it is possible to address the specific\nspin states of a diamond sample using a low power microwave generator.\n
