Design of Q-band loop-gap resonators at frequencies of 34–36GHz for single electron spin spectroscopy in semiconductor nanostructures

We report on the design of loop-gap resonators operating in the frequency range of 34–36GHz with the goal to achieve single electron spin resonance in quantum dot nanostructures. We present a comprehensive study of the magnetic field strength and the spatial distribution of the electric and magnetic fields in the resonator by means of experiments and numerical simulations.
