A novel theory is proposed in this article to design a bandpass frequency-selective surface
(FSS) with a stable angular response. Based on this theory, the performance of the structure …

An ultrathin bandpass frequency selective surface (FSS) with miniaturized unit cell is
proposed in this letter. A significant coupling capacitance can be introduced by the large …

Frequency selective surface (FSS) with ultrawide out-of-band rejection is proposed in this
article. For achieving an ultrawide and high-intensity stopband, a common second-order …

The 2.5-dimensional closed loop is investigated to constitute a novel miniaturized frequency-
selective surface (FSS) whose electric size of one unit cell is as small as 0.048 λ 0× 0.048 λ …

A single-layer substrate frequency selective surface (FSS) made of miniaturized elements is
proposed, with two controllable passbands obtained. Each FSS element consists of a loop …

In this letter, a novel bandpass frequency selective surface (FSS) is proposed. Unlike the
traditional FSSs, our building block makes use of a periodic cell with much smaller size than …

In this communication, an ultra-wide band frequency selective surface (FSS) with excellent
transmission performance in the desired passband and reflection performance in the out-of …

In this letter, a flexible multifunctional active frequency selective surface (AFSS) with
miniaturized units is proposed, and it is simulated, fabricated, and measured. In the …

A novel bandpass frequency-selective surface (FSS) with high selectivity and angular
stability is presented. In the skirts of the narrow passband, two transmission zeros (TZs) are …

In this letter, a low-profile bandpass frequencyselective surface (FSS) that is independent of
incident angle and polarization is proposed. This FSS is composed of two identical metallic …
