“…For instance, THz waves beyond 2 THz are more susceptible to atmospheric absorption, limiting their range in outdoor environments. Additionally, there are fewer available sources and detectors for THz waves beyond 2 THz, making it more difficult to develop practical devices [14][15][16]. Therefore, the 0.2-2 THz range strikes a balance between practicality, performance, and safety, establishing it as the most promising regime for FSS applications.…”

Frequency-selective surfaces are widely employed in spectrometers, selective absorbers, energy harvesting, and sensing devices. In the terahertz range, this ideal component is often limited by the choice of material that adds some degree of attenuation, reducing signal-to-noise ratio. Moreover, these frequency-selective surfaces are often bulky and demonstrate low extinction ratio, that limit their usage in wearables and miniaturised devices. In this work, a multi-band frequency-selective surface composed of periodic microstructures on ultrathin polyimide sheet, is proposed, analysed, fabricated, and evaluated using THz-TDS. The unit cell is composed of triple, evenly spaced, horizontal gold strips, linked around the middle by a fourth vertically oriented gold strip. By displacing the vertical strip, the asymmetric metasurface show dual narrowband transmission at 1.04 THz and 1.67 THz. However, only a single narrowband transmission at 1.07 THz can be observed on a symmetric metasurface, with no displacement. The calculated Q factors are 4.52 and 16.63 at 1.04 THz and 1.67 THz, respectively, for the asymmetric metasurface. While for the symmetric metasurface the calculated Q factor at 1.07 is 3.63. The proposed flexible metasurface can be tailored easily as single or dual narrowband frequency selective metasurface for channel filtering and broadband sources in emerging terahertz wireless systems.

“…It is noted that the FSS elements given here are only with a single resonant frequency. The proposed method can also be suitable for the analysis of dual resonant (e.g., Jerusalem cross, frame-cross), multiple resonant (e.g., multiple square loops), and even more complex FSS elements whose equivalent circuits can be easily obtained [36], [37].…”

“…The performance of a FSS is affected by many factors, including the geometry of the FSS unit cell, substrate material, and mutual coupling between array elements. The different unit cell geometries, including dipole, tripole, Jerusalem cross, spiral, loop, and fractal shapes are comprehensively studied [13][14][15]. Moreover, the development of fabrication technology and the discovery of new materials urge researchers to investigate different substrates thoroughly.…”

In this paper, a flexible bandstop frequency selective surface (FSS) array fabricated on jeans substrate using silver-coated conductive yarn with a computerized embroidery machine is presented for X-band. The S parameters of the fabricated design are measured through the free space method. The measured S-parameters showed significant stopband characteristics between 8 GHz-11.5 GHz for -30o to 30o degrees wide incident angles. Moreover, the transmission, reflection, absorption, and shielding effectiveness (SE) of the FSS array are also computed using measured S parameters. The prototype provides shielding effectiveness of more than 30 dB in X-band and has dominant absorption behavior for some frequencies within the band.
