Journal ArticleDOI
Analytical circuit model for split ring resonators in the far infrared and optical frequency range
TL;DR: In this article, an LC-circuit model for single split ring resonators (SRRs) operating at far infrared and optical frequencies is proposed, taking the effects of magnetic and kinetic inductances as well as gap and surface capacitances into account.
Journal ArticleDOI
Super-resolution for a point source better than λ/500 using positive refraction
Juan C. Miñano,Ricardo Marqués,Juan C. González,Pablo Benítez,V. Delgado,Dejan Grabovičkić,Manuel Freire +6 more
TL;DR: Ma et al. as mentioned in this paper presented steady-state simulations with a non-perfect drain for a device equivalent to the MFE, called the spherical geodesic waveguide (SGW), which predicts up to?/500 super-resolution close to discrete frequencies.
Journal ArticleDOI
Analytical theory of extraordinary optical transmission through realistic metallic screens.
TL;DR: An analytical theory of extraordinary optical transmission through realistic metallic screens perforated by a periodic array of subwavelength holes is presented, which may help to clarify the physics underlying EOT and serve as a first step to more accurate analysis.
Journal ArticleDOI
Surface impedance model for extraordinary transmission in 1D metallic and dielectric screens.
V. Delgado,Ricardo Marqués +1 more
TL;DR: A numerical analysis based on the mode matching technique proves to be an efficient tool for the characterization of these structures for any angle of incidence and slit or defect apertures.
Journal ArticleDOI
Super-resolution for a point source better than {\lambda}/500 using positive refraction
Juan C. Miñano,Ricardo Marqués,Juan C. González,Pablo Benítez,V. Delgado,Dejan Grabovičkić,Manuel Freire +6 more
TL;DR: In this paper, the authors present simulations with a non-perfect drain for a device equivalent to the MFE, called the Spherical Geodesic Waveguide (SGW), that predict up to λ/500 super-resolution close to discrete frequencies.
