Improved FDTD method for studying on graphene frequency selective surface (GFSS) characteristics for nanoelectromagnetics applications

A generalized recursive convolution (RC) FDTD method integrated with subcell technique is proposed for studying on transmission and reflection characteristics of cross-shape graphene frequency selective surface (GFSS) which is biased by an electrostatic field. This improved method is very flexible for efficiently modelling single and even multi-layer dispersive “thin” nano layers together with other dispersive media, which can be used for the development of some novel nano structures for EMC applications operating at very high frequencies. Parametric studies are performed to demonstrate the GFSS performance up to THz band which is controllable or adjusted by the applied electrostatic field.
