In this work, a wideband and high-selectivity amplifying frequency-selective surface (AFSS)
has been proposed. To achieve a wideband FSS, meta vias that are employed to couple …

The physical characteristics of electromagnetic waves are combined with digital information
in coding metasurfaces. Coding metasurfaces enable precise control of beams by flexibly …

In order to implement multiple electromagnetic (EM) wave front control, a reconfigurable
multifunctional metasurface (RMM) has been investigated in this paper. It can meet the …

As metasurfaces are in the spotlight, research is being conducted to incorporate them into
transmitarray (TA) antennas. Among these, as an attempt to create a low-profile design, a …

This paper proposes a broadband power amplifying metasurface with polarization
conversion (PC-PAM). The metasurface is composed of a circular radiating patch on the top …

Programmable metasurfaces have garnered significant attention due to their exceptional
ability to manipulate electromagnetic (EM) waves in real time, leading to the emergence of a …

Amplifier-loaded metasurface has been an efficient way for breaking reciprocity and
realizing power amplification. Here, we proposed a dual-band nonreciprocal transmissive …

This paper presents a design of amplifying metasurface element with polarization
conversion. The element consists of a receiving patch, a power amplifier circuit, and a re …
