In this article, a wideband energy selective surface (ESS) with quasi-elliptic response and
high shielding effectiveness is proposed for providing out-of-band rejection and high-power …

In this paper, we demonstrate a beam-steering antenna using a fluidically programmable
metasurface (FPMS). The proposed FPMS-based antenna consists of a source antenna and …

Abstract The Internet of Things (IoT) devices are distributed randomly in the environment,
antennas with multiple switched beams are needed to unlock the full potential of …

With the emergence of cellular networks, the wireless communication network system has
evolved from the first generation to the sixth generation (6G), which will provide an …

Reconfigurable frequency‐selective surfaces (RFSSs) are of significant interest in
applications, such as secure communication systems or tunable radomes, to improve indoor …

A beam-sweeping antenna utilizing a novel active frequency-selective surface (FSS) is
developed in this letter. It is comprised of a simple dipole and a cylindrical FSS formed by six …

This letter presents a beam‐steering antenna with an active frequency selective surface
(AFSS). The proposed AFSS‐based antenna consists of a source antenna and an active …

This paper presents the development of a reconfigurable corner reflector that uses a PIN-
diode-switched frequency selective surfaces (FSS). A reflector aperture angle of 45° is …

In this paper a varactor-tunable bandstop FSS based on the four arms star geometry is
presented. Besides the resonant frequency tuning, an interesting feature is that practically …

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 …
