Equivalent circuit analysis of left handed SRR loaded metamaterial waveguides
Jorge Carbonell, Luis J. Roglá, Vicente E. Boria
Equivalent circuit analysis of left handed SRR loaded metamaterial waveguides Jorge Carbonell, Luis J. Roglá, Vicente E. Boria Abstract -- This paper reports the Left-Handed (LH) behavior of a novel transmission structure in waveguide technology taking benefit of a negative permeability synthesized via Split-Ring Resonators (SRRs). To overcome some of the existing limitations of previously reporte

Digital phase shifters based on rightand left-handed transmission lines Irina B. Vendik1, Orest G. Vendik2, Dmitry V. Kholodnyak1, Elena V. Serebryakova', Polina V. Kapitanova' Abstract -- Digital phase shifters based on switching between transmission lines with positive and negative dispersion can be designed as miniature microwave devices operating in a wide frequency range. Design of the switch
Broadband highly selective bandpass filter based on a Tapered Coupled-Resonator (TCR) CRLH structure
Hoang Van Nguyen, Christophe Caloz
Broadband highly selective bandpass filter based on a Tapered Coupled-Resonator (TCR) CRLH structure Hoang Van Nguyen, Christophe Caloz Abstract -- A highly selective bandpass filter (BPF) based on a tapered coupled-resonator (TCR) composite right/lefthanded (CRLH) structure is presented. This filter exhibits a measured fractional bandwidth in excess of 110% and can therefore be used in ultra wid
Artificial magnetic conductors enhancing the wave propagation in oversized parallel plate waveguides for planar antenna applications Artificial magnetic conductors enhancing the wave propagation in oversized parallel plate waveguides for planar antenna applications

Application of left handed superstrates to improve radiation performances of dipole antennas , Elena ,Saenz1 Inigo Ederra l , Ramón Gonzalo', Peter de Maagt2 Abstract -- In this paper, radiation properties of dipole antennas with Left Handed Media (LHM) superstrates are analysed. A uniform LHM superstrate with cells tuned to the antenna's resonant frequency and a non-uniform LHM superstrate which
An extended equivalent circuit based FDTD scheme for the efficient simulation of CRLH metamaterials
Andreas Rennings', Simon Otto2, Andreas Lauer2, Cristophe Caloz3, Peter Waldow2
An extended equivalent circuit based FDTD scheme for the efficient simulation of CRLH metamaterials Andreas Rennings', Simon Otto2, Andreas Lauer2, Cristophe Caloz3, Peter Waldow2 Abstract -- A novel formulation of the well-known finite-difference time-domain (FDTD) scheme is proposed. This formulation consists in an extension of the equivalent circuit (EC) description of the Yee cell including a
