Resolving scattering in complex media: a hybrid THz model for multilayer building materials
Year: 2026
Type: article
Abstract: Accurate terahertz scattering models for multilayer building materials are vital for the design of 6G systems, but current methods are either too simple or computationally expensive. We introduce a hybrid multilayer scattering model that unites a recursive method for coherent scattering with the scalar Kirchhoff approximation for the incoherent portion; a physics-based coefficient partitions power between these components. Compared with the experimental data, the proposed model can decrease the root-mean-square error by as much as 89.6 % when modeling complex laminated materials. The proposed model is a physically robust and computationally efficient tool for designing THz imaging tools and indoor 6G networks.
