Satellite communications (SatComs) have recently entered a period of renewed interest
motivated by technological advances and nurtured through private investment and ventures …

The intent of this paper is to provide an overview of basic concepts, types, techniques, and
experimental studies of the current state-of-the-art Frequency Selective Surfaces (FSSs) …

Reconfigurable metasurfaces have attracted much attention in recent years due to their
flexible capabilities of manipulating electromagnetic (EM) waves. However, most of the …

Future satellite platforms and 5G millimeter wave systems require Electronically Steerable
Antennas (ESAs), which can be enabled by Microwave Liquid Crystal (MLC) technology …

In this paper, a novel polarization-reconfigurable converter (PRC) is proposed based on a
multilayer frequency-selective surface (MFSS). First, the MFSS is designed using the square …

Polarization control of electromagnetic (EM) waves is vital in imaging and wireless
communication systems. In this communication, we propose a broadband polarization …

This communication presents a liquid crystal (LC)-based electronically tunable metamaterial
unit cell that can serve as a building block for dynamic metasurface antennas (DMAs). The …

A wide-angle scanning circularly polarized (CP) antenna array based on a novel polarizer is
proposed. The working mechanism is that the linear polarization (LP) substrate integrated …

In this paper, a reconfigurable reflectarray (RA) with two-finger element composed of
electrically biased liquid crystal (LC) at millimeter wave band is proposed. An orthogonal …

Liquid crystal technology has a long well-established history of applications in visible light,
primarily in the display industry. In contrast, applications at lower frequencies (microwave …
