Tunable millimeter and sub-millimeter spectral response of textile metamaterial via resonant states

Abstract

We report on a new textile metamaterial created by adding metal wires directly into the polymer yarn. Split-ring resonator-like extended states are created. Simulations revealed that the extended states can be easily tuned via the geometry. Measurements of the transmittance spectrum as a function of the polarization angle in the low terahertz range were also performed and these peaks were ascribed to a polarization-dependent resonator model. The fabrics are viable candidates for flexible and deformable gigahertz and terahertz-enabled metamaterials.

Embroidered Spoof Surface Plasmon Polariton Transmission Line for Wireless Body Sensor Network

“…This technology looks like a flexible Printed Circuit Board (PCB) with two textiles as substrate and conductive patterns, and other textile technologies might be more convenient for end users. Although all the textile technologies as knitting, weaving, and embroidery were already proposed for integrating antennas or filtering functions in smart textiles [19][20][21], embroidery has become the most popular because of the ease of fabrication [19,[22][23][24]. However, there are some drawbacks compared to more traditional technology such as flexible PCB, which have to be taken into account in the design stage.…”

Woven metamaterials with an electromagnetic phase-advance for selective shielding

“…Then new applications have been considered as perfect lens previously theoretically proposed by Veselago [7], perfect electromagnetic absorbers [2], or the invisibility cloak to hide objects surrounded by a metamaterial [8]. A lab scale textile inspired technology has been proposed [9], and negative refractive index appearing as a phase-advance of the electromagnetic wave transmitted through a textile metamaterial have been measured [10]. …”
