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 …

In this paper, a 2.5-D approach has been used to design 2.5-D miniaturized multifunctional
active frequency-selective surfaces (2.5-D MMAFSSs). The unitary element, based on the …

In this letter, a broadband switchable active frequency selective surfaces (AFSSs) is
presented, and the proposed structure is comprised of three metallic layers and two Rogers …

A miniaturized dual-bandstop frequency selective surface (FSS) using convoluted structures
is proposed in this letter. The working central frequencies of the proposed FSS are 2.66 and …

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 …

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 …

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 …

This letter proposes a 4-bit multifunctional active frequency selective surface (AFSS) whose
structure is made up of two metallic layers arranged on both sides of a 1.6 mm thick FR-4 …

A new dual-band frequency selective surface (FSS) is introduced in this paper. By having a
miniaturized unit cell size, the proposed FSS transmission response shows minimal …

In this letter, a single-layer frequency selective surface (FSS) with high angular stability is
proposed. By combining two modified cross loops, the proposed combined FSS (CFSS) …
