A thin conducting sheet (TCS) model in 3D FDTD : Implementation and validation

We present in this article the extension to the 3D case of an original thin conducting sheet (TCS) model developed in for 1D FDTD simulations. This method is based on the use of time domain admittance operator as a sub-cell model of the conducting layer. We present the 3D scheme and report on validations that have been conducted and that demonstrate the ability of the model to deal with noticeable skin effect.
