Accurate Calculation of Tensor Surface Impedance Using Scattering Analysis

In this work, we present a scattering analysis approach for accurate calculations of tensor surface impedance that is highly time efficient than using eigenmode analysis. While previous work has shown this method for the case of scalar impedance, our work generalizes the approach for tensor impedance. Extensive numerical simulations are shown for both scalar and tensor impedance in support of the efficacy and accuracy of our results. We observe that the results obtained using eigenmode analysis with finer simulation settings which are computationally expensive converge to the results obtained using our method with scattering analysis.
