Pulsed electron spin resonance (ESR) is a technique that has found many applications in the fields of chemistry and biology. In order to enhance its sensitivity by several orders of magnitude, one can use on chip superconducting resonators with high quality factors. However, they also introduce new challenges because of their narrow bandwidth and nonlinear behavior. In this talk, I will describe our proposed solution to overcome these challenges in the context of measuring spectra, along with simulations and NMR measurements supporting its utility.In the second half of my talk, I will introduce the k-space formalism, a reciprocal space description often used in MRI. This method allows us to track the effect of evenly spaced pulses and a gradient drift hamiltonian on an ensemble of non-interacting spins. I will extend the existing description to incorporate the use of a frequency sweep, and demonstrate that it can be used in a continuum limit to understand the effect of any arbitrary control pulse.
