Abstract
A methodology for the accurate and efficient modelling of thin surfaces, containing either frequency-dependent homogeneous materials or heterogeneous pseudo two-dimensional joints, in time-domain computer codes is presented. The approach is based on a two-sided surface impedance boundary condition “macro-model” representation of the material or joint. The macro-model is derived from scattering matrix data obtained from either measurements or high resolution simulations that is processed using conditioning and optimization algorithms to produce a digital filter representation of the impedance matrix elements. The digital filters are realized in a finite-difference time-domain code as a second-order section cascade filter using a novel face-centred explicit update scheme.
