    "description": "Included here are figures and other relevant data from the paper \"Measurements of nonlinear polarization dynamics in the tens of GHz\" to be published in Physical Review Applied.Abstract: Frequency-dependent linear permittivity measurements are commonplace in the literature, providing key insights into the structure of dielectric materials. These measurements describe a material's dynamic response to a small applied electric field. In contrast, nonlinear dielectric materials are widely used for their responses to large applied fields, including switching in ferroelectric materials, and field-tuning of the permittivity in paraelectric materials. These behaviors are described by nonlinear permittivity. Nonlinear permittivity measurements are fraught with technical challenges because of the complex electrical coupling between a sample and its environment. Here, we describe a technique for measuring the complex nonlinear permittivity that circumvents many of the difficulties associated with other approaches. We validate this technique by measuring a the nonlinear permittivity of a tunable Ba0.5Sr0.5TiO thin film up to 40 GHz and comparing our results with a phenomenological model. These measurements provide insight into the dynamics of nonlinear dielectric materials down to picosecond timescales.",
