Ethanol-Water mixtures S_21 magnitude measurements with honeycomb planar CSRR

Measurements of the magnitude of the scattering parameter S21 on a planar honeycomb CSRR sensor for different concentrations of water–ethanol mixtures:
1) Five folders corresponding to different measurement dates and times, named in the format yyyymmdd_hhmm.
2) Inside each yyyymmdd_hhmm folder, there is one xYY folder per ethanol concentration in water (from 10% vol to 90% vol), a baseline .csv file, and a file containing the randomized measurement order.
3) Inside each xYY folder, there are 10 .csv files named as follows: xYY_vZZ_yymmdd, where YY denotes the concentration and ZZ denotes the vial number of the sample.
4) This dataset corresponds to a published open-access study. For further information about the sampling methodology, please refer to:
