Compact Balanced Dual-Band Bandpass Filter Based on Modified Coupled-Embedded Resonators
TL;DR: In this paper, a balanced dual-band bandpass filter based on coupled-embedded resonators with modified ground plane is presented, where common mode is rejected within the two differential passbands by symmetrically introducing four coupled U-shaped defected ground structures below the resonators.
Journal ArticleDOI
Experimental verification of extraordinary transmission without surface plasmons
Francisco Medina,Jorge A. Ruiz-Cruz,Francisco Mesa,Jesús M. Rebollar,Jose R. Montejo-Garai,Ricardo Marqués +5 more
TL;DR: In this paper, an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm is provided, where the standard surface plasmon polariton (SPP) theory does not apply.
Journal ArticleDOI
Analytical theory of wave propagation through stacked fishnet metamaterials.
TL;DR: This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly and shows that, apart from Fabry-Perot resonances, these structures support two transmission bands that can be backward under the appropriate conditions.
Journal ArticleDOI
Design of Wide-Band Semi-Lumped Bandpass Filters Using Open Split Ring Resonators
TL;DR: Open split ring resonators (OSRRs) are used in this paper to design wide-band semi-lumped bandpass filters, which can be then used as building blocks of reduced size band pass filters.
Journal ArticleDOI
Simplified Circuit Model for Arrays of Metallic Dipoles Sandwiched Between Dielectric Slabs Under Arbitrary Incidence
Maria Garcia-Vigueras,Francisco Mesa,Francisco Medina,Raul Rodriguez-Berral,Jose Luis Gomez-Tornero +4 more
TL;DR: In this paper, an equivalent circuit is proposed to model the transmission/reflection of a plane wave that impinges obliquely on a periodic arrangement of metallic rectangular dipoles embedded between two dielectric slabs.
