Metamaterial-based waveguides offer unusual properties compared to conventional metallic and dielectric waveguides. We experimentally investigate a novel waveguide with an air-core and a cladding formed of slotted cylinder resonators, which can have an electric and/or a magnetic response at terahertz (THz) frequencies, depending on their orientation and the polarization of the light, and through these...
Metamaterial-based waveguides offer unusual phenomena compared to conventional metallic and dielectric waveguides. We present a novel waveguide based on metamaterials, an air-core waveguide with a magnetic metamaterial cladding assembled from split ring resonator fibers. The transmission properties of the waveguide in the terahertz region are characterized both experimentally and numerically. Such...
Fibre drawing technology can be used to fabricate large quantities of metamaterials with designer electromagnetic response, for THz, infrared and beyond. We present a summary of our progress in the field, including experimental demonstrations of THz hyperlenses, infrared metamaterial fibres, and the path to shorter wavelengths.
Fibre drawing techniques are used to produce metamaterials with electric and magnetic responses for the terahertz and far-infrared spectrum. This technique can be scaled to mass production and operation at optical wavelengths.
The extraordinary potential properties of metamaterials have resulted in great interest in overcoming the challenges of fabricating them in useful quantities. We have drawn fibres incorporating metamaterials with engineered permittivity and permeability at THz wavelengths.
We characterize resonances of 3D fiber metamaterials under transmittance at oblique incidence. The resonance frequency of longitudinally invariant resonators increases with the incident angle, while the resonance of disconnected resonators does not.
Metamaterials offer extraordinary optical properties, however they are challenging to make. We apply fiber drawing to fabricate volume metamaterials in quantity. We demonstrate metamaterials with engineered permittivity and permeability at THz.
We fabricate terahertz metamaterials with negative magnetic permeability by combining fiber drawing and silver sputtering. We experimentally and numerically characterize the transmittance of spooled metamaterial arrays with different orientations.
