Dual capacitive-inductive nature of graphene metasurface: Transmission characteristics at low-terahertz frequencies. En IEEE Antennas and Propagation Society International Symposium (1598-1599), Orlando, USA: Institute of Electrical and Electronics Engineers.978-1-4673-5317-51522-39651947-1491https://hdl.handle.net/11441/97272We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned graphene exhibits both the low-frequency (capacitive) passband of metal patch arrays and the higher-frequency (inductive) passband of metal aperture arrays in a single tunable configuration. The analysis is carried out using a transfer matrix approach with two-sided impedance boundary conditions, and the results are verified using full-wave numerical simulations.application/pdf2 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1109/APS.2013.671145820613144
