In this paper, an active bandstop frequency selective surface is proposed, where the
frequency and the magnitude at the resonant transmission dip can be tuned independently …

A novel dual-band electronically beam scanning antenna based on a slot active frequency-
selective surface (SAFSS) is proposed in this article. Each unit cell used in an SAFSS screen …

With the proliferation of smart devices, the Internet of Things (IoT) is rapidly expanding. This
study proposes a miniaturized controllable metamaterial with low control voltage for …

In this work, a varactor-tunable frequency selective surface (FSS) is proposed; it is based on
a common FSS composed of annular ring slot cells, in which four varactors are loaded on …

In this paper, a wideband low-profile cylindrical conformal array antenna with flexible beam
scanning capability is reported. The design consists of the semi-cylindrical band-pass array …

In this study, a novel structure, which is applied to different metal layers of ultra-wideband
frequency selective surfaces (FSS), is proposed. It has been found that by adjusting the size …

This letter describes a reconfigurable frequency‐selective surfaces (FSSs) unit cell using
cantilever switches resonating at X‐band frequency. The shape of the FSS is inspired by …
