Abstract
A novel method is proposed to treat thin conductive (TC) sheets of arbitrary three-dimensional shape and curvature with the electromagnetic (EM) finite-difference time-domain (FDTD) algorithm without the need to resolve the sheet thickness spatially. It is shown that due their physical properties. TC sheets can be modeled without introducing additional field components to the conventional Yee scheme. Due to this noninvasive approach, in addition to the preserved stability of the FDTD algorithm. the method can be directly applied to any existing FDTD kernel, such as parallelized or hardware accelerated versions. The method, implemented within the framework of a professional EM FDTD software package, has been developed to be applied to and tested on real-world applications such as mobile phones.
