The super Gaussian-based Goos–Hänchen shift is investigated in a tunneling five-level chiral atomic medium for left and right circularly polarized LCP/RCP beams. Crater-type reflection and transmission are reported for LCP and RCP beams. The power of super Gaussian plays a key role in the Goos–Hänchen shift. The highest level of negative reflection for RCP and LCP beams is calculated to be \(R^{(\pm )}=-0.3\) , and the highest of negative transmission for RCP and LCP beams is calculated to be \(T^{(\pm )}=-1.5\) . The sum of coefficients of absorption, reflection, and transmission obeys the normalization condition, i.e., (A+R+T=1). Positive reflection and transmission shifts are reported for both LCP and RCP beams in five-level chiral atomic medium. The highest shift in reflection for RCP and LCP beams is investigated to \(+5.6 \lambda\) , and the highest shift in transmission for RCP and LCP beams is investigated to \(+8.25 \lambda\) in the position ranges of \(-1\upmu \textrm{m}\le x,y\le 1\upmu \textrm{m}\) . The obtained results are significant for optical sensors, photonics, plasmonics, and metamaterial technology.
