Theoretical analysis of graphene nanoantennas with different shapes

In this article, we present a numerical analysis of graphene nanoantennas with rectangular, elliptical, triangular, and circular geometries in terahertz band. We model the electromagnetic scattering of these planar structures by the method of moments with the surface impedance of graphene. We analyz...

Description
Summary:In this article, we present a numerical analysis of graphene nanoantennas with rectangular, elliptical, triangular, and circular geometries in terahertz band. We model the electromagnetic scattering of these planar structures by the method of moments with the surface impedance of graphene. We analyze the absorbing cross section and the resonances of nanoantennas for different, sizes, chemical potential, temperature, and incident angle. The obtained results can be useful to design efficient nanoantennas for terahertz wireless communications. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1019–1024, 2014
