An ultrawideband dual-polarized frequency-selective absorber (FSA) with a tunable
reflective notch is proposed in this communication. The structure is constructed by …

In this letter, a dual-band tunable bandstop frequency selective surface (FSS), which is
capable of exhibiting independent tuning for the top and bottom layers, has been presented …

A novel polarization-independent reconfigurable frequency selective surface (FSS) for RF
shielding is proposed in this letter. The FSS is designed on a flexible and transparent …

A polarization-insensitive tunable frequency selective surface absorber for oblique
incidence broadband applications is presented. The design method of combining anisotropy …

A design approach for dual-passband frequency-selective surface (FSS) with independent

This paper presents an optically transparent active bandstop frequency selective surface
(FSS) with wideband tunability of two resonance frequencies using the concept of …

This paper is presented to provide an overview on frequency selective surfaces and
techniques to achieve tune-ability in frequency selective surface (FSS). FSS array element …

We propose dual-band filters made from a single-layer metasurface for operating on the 28
and 39 GHz bands in mm-wave fifth generation (5G) communication systems. We use the …

Shape-changing mechanical metamaterials have drawn the attention of researchers toward
the development of continuous-range tunable frequency selective surfaces (FSSs). In this …

In this paper, a tunable triband frequency selective surface unit cell based on varactor-
loaded split ring slots is presented. By using the third resonant mode, a considerable mutual …
