Metamaterials (MMs) with artificial structures have extraordinary physical properties that
cannot be found in traditional materials. MMs with electromagnetic wave absorption (MMAs) …

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

A gain-enhanced antenna consisting of a bandpass frequency selective surface (FSS) and a
patch antenna is initially proposed in this communication. By utilizing the reflection …

In this article, a novel design of compact frequency-selective rasorber exhibiting absorption–
transmission–absorption characteristics and having high passband selectivity has been …

In this article, a low radar cross section (RCS) and high-gain Fabry–Pérot (FP) antenna with
reconfigurable scattering beams based on varactor diodes is proposed. The partially …

A frequency-selective surface (FSS) can be employed as a spatial filter for incident
electromagnetic (EM) waves, which are most often used in radome design to protect the …

A strategy for folded reflectarray with low detectability and enhanced gain is presented. For
this purpose, the folded reflectarray is engineered by combining a polarization-conversion …

This letter presents a novel polarization conversion metasurface (PCM) which is used for the
design of a low-profile low-radar cross section (RCS) multiple-input-multiple-output (MIMO) …

To avoid being detected by radar, it is necessary to reduce stealthy military platforms' radar
cross section (RCS). The operation of overlaying the metasurface (MS) on the targets is a …

Deep neural networks (DNNs) are widely used in designing a metasurface; however, data
acquisition from simulations is expensive in terms of time and effort. Inspired by image …
