Photonic band gap spectra in Octonacci metamaterial quasicrystals
(Elsevier, 2017)
New Matter Properties and Applications based on Hybrid Graphene-based Metamaterials
(Bentham Science, 2020-05)
Graphene as an organic material has gained special attention due to their electronic and conductive properties. Moreover, its highly conjugated chemical structures and relative easy modification have allowed varied design ...
Bulk-plasmon polaritons in metamaterial-metamaterial one-dimensional photonic superlattices
(Academic Press Ltd- Elsevier Science LtdLondonInglaterra, 2013)
Uso de metamaterial no tratamento acústico de painel duplo
(2019)
Há diversos parâmetros para classificar a qualidade de uma aeronave, entre eles encontrase a qualidade sonora no seu interior. Desta forma, incrementar a capacidade que a parede de uma aeronave tem em atenuar sons externos ...
Scattering of light from metamaterial gratings with finite length
(OSA - The Optical Society, 2012-08)
Using an integral equation approach based on the Rayleigh hypothesis, we investigate the scattering of a plane wave at the rough surface of a metamaterial with a finite number of sinusoidal grooves. To show the adequacy ...
Influence of the sign of the refractive index in the reflectivity of a metamaterial surface with localized roughness
(Springer, 2011-06)
To study the scattering properties of metamaterials, we generalize two scattering methods developed for conventional (non-magnetic) isotropic materials to the case of materials with arbitrary values (positive or negative) ...
Signature of bulk longitudinal plasmon-polaritons in the transmission/reflection spectra of one-dimensional metamaterial heterostructures
(Academic Press Ltd- Elsevier Science LtdLondonInglaterra, 2013)
Caracterização de antenas planares com substrato metamaterial
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2011-11-25)
This work presents a theoretical and numerical analysis for the radiation
characteristics of rectangular microstrip antenna using metamaterial substrate. The full
wave analysis is performed in the Fourier transform domain ...
