Included Files of this repository are:

1_AcceptedManuscript_BeamSensingBesselMetasurface_IEEETHz_TSNowack.pdf is the author accepted version of the main text of the manuscript

2_SupplementInfo_BeamSensingBesselMetasurface_IEEETHz_TSNowack.pdf is the supplemental file explaining underlying methodologies and techniques in more detail, 
i.e. meta-pillar simulations, pattern generation code, fabrication, telecentric objective and polarimetric image analysis.

3_PNGFigures is a folder containing 600dpi color versions of illustrations in .png format of both the main text (incl. author pictures) and supplementary Information.

4_MetasurfaceDesign&PatternGeneration is a folder containing 
  a) The Simulation files and results for each meta-pillar geometry (pillar widths Wx, Wy and height H)
  b) The Metasurface pattern generation code (python) to create the metasurfaces from the previously simulated meta-pillar geometries, as well as the simulated and fabricated metasurfaces of this publication in .gds file format.

5_MetasurfaceSimulations&Model is a folder containing
  a) The Lumerical FDTD Simulation files of this publication.
  b) The Analytical model describing the axial SoP variations of the investigated metasurface design.

6_ExperimentalResults is a folder containing
  a) Fabrication results, i.e.white light interferometry data on the dry-etched metasurface and SEM images, as well as the Cross-section of both orthogonal phase profiles and their expected Error margin due to the observed etch-depth variation caused by Aspect-ratio dependent etching.
  b) Experimental Setup, i.e. Zemax OpticStudio simulations of the 7.7x magnifying telecentric objective used for optical experiments.
  c) Sensing Experimental Results, i.e. Raw image data and matlab code underlying the polarimetric image analysis for i) the Calibration Scan in Air ii) the Diattenuation Sensing with wire grid polariser and iii) refractive index sensing with 5.65mm thick HDPE slab.
