Properties of magnetically coupled metamaterial elements
The birth of the subject of metamaterials, including many early contributions, is briefly reviewed. More specifically, a relatively new topic, the properties of waves on magnetically coupled metamaterial elements are discussed with particular reference to their dispersion characteristics, excitation and applications. r 2005 Elsevier B.V.

متن کاملMagnetically Tunable Ferrite-Dielectric Left-Handed Metamaterial
In this paper, a magnetically tunable metamaterial is proposed and studied. The metamaterial is based on the combination of ferrite sheets and dielectric rods. The tunable property is originated from the ferromagnetic resonance and electric response of dielectric rods. The retrieved electromagnetic parameters and transmission characteristic showed that by simultaneously inspiring the ferromagne...
متن کاملDesign, Fabrication and Measurement of Two-Layered Quadruple-Band Microwave Metamaterial Absorber
The design, simulation, fabrication, and measurement of two structures of metamaterial absorbers (MA) is investigated at microwave frequency in this paper. By stacking of one layer structure on the top of each other, a two-layered structure is generated. The unit cell at each layer consisting of two sets of various circular and square patches are designed so that the structure exhibit quad band...
متن کاملContinuously tunable terahertz metamaterial employing magnetically actuated cantilevers.
Terahertz metamaterial structures that employ flexing microelectromechanical cantilevers for tuning the resonance frequency of an electric split-ring resonator are presented. The tuning cantilevers are coated with a magnetic thin-film and are actuated by an external magnetic field. The use of cantilevers enables continuous tuning of the resonance frequency over a large frequency range. The use ...
متن کاملA Planar, Layered Ultra-wideband Metamaterial Absorber for Microwave Frequencies
In this paper, an ultra-wideband metamaterial absorber is designed and simulated. The proposed absorber is planar and low profile. It is made of a copper sheet coated with two dielectric layers. Each unit cell of the metamaterial structure is composed of multiple metallic split rings, which are patterned on the top and middle boundaries of the dielectrics. The designed absorber utilizes differe...
