Metasurfaces are ultrathin, two-dimensional structures composed of periodic or quasi-
periodic arrays of sub-wavelength scatterers. They possess the unique ability to …

A novel technique for designing ultrabroadband radar cross section (RCS) reduction
surfaces using artificial magnetic conductors (AMCs) is proposed in this paper. This …

A new approach for the gain enhancement and wideband radar cross section (RCS)
reduction of an antenna based on the chessboard polarization conversion metasurfaces …

This review discusses the evolution of the various radar cross-section (RCS) reduction
techniques, with an emphasis on metasurfaces. The paper first introduces the terms RCS …

In recent decades, metasurfaces have attracted considerable interest to generate vortex
beams, that is, orbital angular momentum (OAM) carrying beams. However, the existing …

We report the design, fabrication, and measurement of an ultra-broadband wide-angle
reflective cross-polarization convertor using the compact H-shaped metasurface. The …

This communication presents a low-profile, compact, high gain dual-band and dual-
circularly polarized (CP) folded transmitarray antenna (FTA) with independent beam control …

In this paper, low-profile broadband planar folded transmitarray antennas (FTAs) are
proposed and studied based on a novel Fabry-Perot polarizer. A novel element is proposed …

Reflection reduction metasurface is capable of suppressing the radar cross section of a
target, which is of great importance in stealth technology. However, it is still a challenge to …

In this paper, an ultra-broadband and high-efficiency polarization conversion metasurface is
presented in the terahertz region. The metasureface is similar to a sandwiched structure …
