The dataset Provides S-parameter measurements of an AI enhanced wireless power transfer system using two ISO/ICE 14443-1 Coils with series capacitance compensation at 13.56 MHz under three configurations of vertical and horizontal misalignment, inter-coil distance, and azimuthal tilt. The structure and components of the system is shown in the Image attached to the Dataset This measured data validates the implementation of the system at the three coil configurations discussed in the publication.

The Dataset complements the data we provided in the separate dataport under the following DOI: 10.21227/vtp8-x586



Detailled Instructions indicating how to handle the provided measurements are found in the "Readme.pdf" . An example matlab function "TestPerformanceWPT" showing how to handle the measured data has been provided . Additionally, a set of custom auxiliary matlab functions called "Find_TargetFreqIndex", "GenerateMacroDataset", and "SmithPlotTargetFreq"  have been provided. Additionally, two data folders MeasData.zip and MeasDataWPT.zip has been provided. The matlab functions and this data should all stay in the same root folder.
