Magnetically tunable Mie resonance-based dielectric metamaterials
Electromagnetic materials with tunable permeability and permittivity are highly desirable for wireless communication and radar technology. However, the tunability of electromagnetic parameters is an immense challenge for conventional materials and metamaterials. Here, we demonstrate a magnetically tunable Mie resonance-based dielectric metamaterials. The magnetically tunable property is derived...
متن کاملDesign of a Single Negative Metamaterial based Microstrip Patch Antenna
This paper describes the design and simulation of the new Ɛ negative metamaterial unit cell structure and then the unit cells are combined to form 3D array which use as metamaterial cover with a single microstrip patch antenna. The new Ɛ negative metamaterial is based on the ELC resonator structure, which is used for obtaining the negative value of permittivity and positive value of permeabilit...
متن کاملQ-based design equations for resonant metamaterials and experimental validation
Practical design parameters of resonant metamaterials, such as loss tangent, are derived in terms of the quality factor Q of the resonant effective medium permeability or permittivity. Through electromagnetic simulations of loopbased resonant particles, it is also shown that the Q of the effective medium response is essentially equal to the Q of an individual resonant particle. Thus, by measuri...
متن کاملA New Circular Polarization Metamaterial Ferrite Phase Shifter
In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...
متن کاملTransmission and Reflection Properties of Composite Double Negative Metamaterials in Free Space
We report free space transmission and the first reflection measurements of a composite double negative (DNG) metamaterial, also known as a left-handed material (LHM). The metamaterial composes of the split-ring-resonators and discontinuous thin wires. Very high transmission values of the metamaterial are observed within a frequency range for which both effective permeability and permittivity ar...
