Metasurfaces, composed of 2-D planar arrays of sub-wavelength metallic or dielectric
scatterers, have provided unprecedented freedoms in manipulating electromagnetic (EM) …

Manipulating the polarizations of electroagnetic waves by flexible and diverse means is
desirable for myriad microwave systems. More recently, metasurfaces have emerged as …

Metamaterials offer the freedom to manipulate the polarization states of light at the
subwavelength scale. However, previous designs generally made use of single resonance …

An ultrathin broadband metasurface-based absorber, comprised of tungsten nanowires, was
studied under the normal and oblique incidence of transverse electric (TE) and transverse …

In this work, an ultra-wideband and high-efficiency reflective linear-to-circular polarization
converter based on an anisotropic metasurface is proposed, which is an orthotropic structure …

substrate-integrated gap waveguide (SIGW)-fed metasurface antenna (metantenna) array
with nonuniform excitation is proposed for wideband operation and sidelobe-level (SLL) …

Here, we propose a low-profile polarizing technique integrated in a parallel plate waveguide
(PPW) configuration, compatible with fully metallic geodesic lens antennas. The geodesic …

A broadband folded transmitarray antenna (FTA) with ultralow-profile, high-gain, and high
polarization purity is proposed in this communication. It consists of a focusing metasurface …

This study presents a linear-to-circular polarization conversion metasurface (PCM) based on
a novel unit cell for a circularly polarized (CP) Fabry-Perot (FP) antenna. The unit cell …

A broadband and wide-angle scanning linear polarization (LP)-to-circular polarization (CP)
converter based on a dual-layer structure is presented. The elementary cell is composed of …
