Journal ArticleDOI
Equivalent-circuit models for split-ring resonators and complementary split-ring resonators coupled to planar transmission lines
Juan D. Baena,Jordi Bonache,Ferran Martin,R.M. Sillero,Francisco Falcone,Txema Lopetegi,Miguel A. G. Laso,Joan Garcia-Garcia,Ignacio Gil,M.F. Portillo,Mario Sorolla +10 more
TL;DR: In this paper, a new approach for the development of planar metamaterial structures is developed, and analytical equivalent circuit models are proposed for isolated and coupled split-ring resonators/CSRRs coupled to planar transmission lines.
Journal ArticleDOI
Babinet principle applied to the design of metasurfaces and metamaterials.
Francisco Falcone,Txema Lopetegi,Miguel A. G. Laso,Juan D. Baena,Jordi Bonache,Miguel Beruete,Ricardo Marqués,Ferran Martin,Mario Sorolla +8 more
TL;DR: A new particle, the complementary split rings resonator, is proposed for the design of metasurfaces with high frequency selectivity and planar metamaterials with a negative dielectric permittivity.
Journal ArticleDOI
Effective negative-/spl epsiv/ stopband microstrip lines based on complementary split ring resonators
TL;DR: In this article, a super-compact stopband microstrip structure is proposed, where the frequency gap is produced by an array of complementary split ring resonators (CSRRs), a concept proposed for the first time on the ground plane.
Journal ArticleDOI
Artificial magnetic metamaterial design by using spiral resonators
TL;DR: In this article, a spiral resonator (SR) was introduced as a useful artificial atom for artificial magnetic media design and fabrication, and a simple theoretical model which provides the most relevant properties and parameters of the SR was presented.
Journal ArticleDOI
Microwave filters with improved stopband based on sub-wavelength resonators
Joan Garcia-Garcia,Ferran Martin,Francisco Falcone,Jordi Bonache,Juan D. Baena,Ignacio Gil,Esteve Amat,Txema Lopetegi,Miguel A. G. Laso,J.A.M. Iturmendi,M. Sorolla,Ricardo Marqués +11 more
TL;DR: In this article, the authors demonstrate the potential of sub-wavelength resonators, namely, split-ring resonators and complementary split ring resonators to suppress undesired spurious bands in microwave filters, a key aspect to improve their rejection bandwidths.
