发明名称 SPINWAVE BASED NONDESTRUCTIVE MATERIAL, STRUCTURE, COMPONENT, OR DEVICE TESTING TOOLS
摘要 Systems and methods for spinwave-based metrology in accordance with embodiments of the disclosure involve generating and detecting spinwaves in a sample having a ferromagnetic material; and determining a material thickness, a material integrity measure, a presence of a manufacturing defect, a categorical type of manufacturing defect, and/or a manufacturing process statistic corresponding to spinwave behavior in the sample. In an embodiment, spinwaves are generated by way of concurrent exposure of a target measurement site of the sample to each of a bias magnetic field and radiation (e.g., microwave or radio frequency radiation) produced by a first set of integrated waveguides. A response signal corresponding to a behavior of spinwaves within the target measurement site can be generated by way of a second set of integrated waveguides. Various embodiments of systems and methods for generating spinwaves, detecting spinwaves, and calculating, analyzing, or monitoring one or more sample properties can be automated.
