Novel methodology derives refractive index profiles from S11 measurements in boreholes, suggesting precision improvements for neutrino detection.
We present a novel methodology for extracting firn ice properties using reflection coefficients (`S11') of antennas lowered into boreholes. Experiments like the Radio Neutrino Observatory in Greenland (RNO-G) require precise firn index of refraction profiles for accurate reconstruction of incident neutrinos and cosmic rays. Using a data-driven method guided by neutron probe measurements in the vicinity of Summit Station, a depth-dependent S11 profile can be translated into a refractive index profile. We present results based on data taken in August, 2024 and May, 2025 from boreholes at Summit Station, Greenland.
