Resumo:
In this work, it is developed a mathematical formulation for modelling Graphene sheets in the three-dimensional lattice used to solve Maxwell’s equations with Yee’s algorithm. The technique is based on piecewise linear recursive convolution method and on thin material sheets technique, valid in intraband range. The HFSS software is used for to designing, for the first time, graphene antennas with dynamic control of the radiation pattern main lobe by tuning the chemical potential of graphene sheets used as passive elements. The numerical method developed in this work fully agrees with the results obtained by using HFSS (this one is based on the Finite Element Method).
