Experimental validation of a Ku-band dual circularly polarized metasurface antenna
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ... -
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ... -
Metamaterials and their application in the performance enhancement of reconfigurable antennas: a review
Metamaterials exhibit properties in terms of subwavelength operation or phase manipulation, among others, that can be used in a variety of applications in 5G communication systems. The future and current 5G devices demand ... -
A metasurface-based single-layered compact AMC-backed dual-band antenna for off-body IoT devices
In this article, a compact printed monopole dual-band antenna using artificial magnetic conductor (AMC)-plane with improved gain and broader bandwidth, applicable for off-body internet of things (IoT) devices is presented. ... -
Metasurface-based ultrathin carpet cloaks for millimeter waves
A metasurface carpet cloak for millimetre-wave range with polarization independent performance is experimentally demonstrated. It is shown that the cloak is able to mimic the ground plane by fully restoring the amplitude ... -
Super-oscillatory metalens at terahertz for enhanced focusing with reduced side lobes
In this paper, we design and numerically demonstrate an ultra-thin super-oscillatory metalens with a resolution below the diffraction limit. The zones of the lens are implemented using metasurface concepts with hexagonal ... -
Terahertz sensing based on metasurfaces
The terahertz (THz) band has very attractive characteristics for sensing and biosensing applications, due to some interesting features such as being a non-ionizing radiation, very sensitive to weak interactions, thus, ... -
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ... -
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
In this communication, an ultrathin transmissive half-wave plate (HWP) based on a bi-layered zigzag metasurface operating at the lower frequency edge of the terahertz (THz) spectrum is numerically and experimentally studied. ...
