A digital twin for a nanophotonically enhanced chiral sensing platform was developed to predict and analyze circular dichroism (CD) measurements. The platform uses helicity-preserving optical cavities to significantly enhance the weak CD signal of chiral molecules. JCMsuite's finite element method solver was used to compute the T-matrices of the nanostructured cavity components, which are essential for the fast and efficient simulation of the entire system's optical response.
