Abstract

A feedback system that identifies characteristics of an object and utilizes the characteristics to initiate and adjust a field applied to the object is provided. The system includes an array of array phase elements made of metamaterials that allow precise shaping of the field to be applied to a particular portion of an object based on characteristics of the object, including location and thickness of the object. Sensors are utilized during supercooling to monitor a condition of the object being supercooled. Specifically, characteristics of the object are measured at different points, areas, or volumes on the object and the measurements are used to determine whether supercooling (or another desired result) is being achieved or whether the object is starting to freeze. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the object without freezing.
