A broadband polarization-insensitive cloak based on mode conversion
In this work, we demonstrate an one-dimensional cloak consisting of parallel-plated waveguide with two slabs of gradient index metamaterials attached to its metallic walls. In it objects are hidden without limitation of polarizations, and good performance is observed for a broadband of frequencies. The experiments at microwave frequencies are carried out, supporting the theoretical results very...
متن کاملConformal cubical 3D transformation-based metamaterial invisibility cloak.
A conformal cubical transformation-based metamaterial invisibility cloak is presented and verified, in the near and the far field, by a rigorous full-wave numerical technique based on a higher-order, large-domain finite element method, employing large anisotropic, continuously inhomogeneous generalized hexahedral finite elements, with no need for discretization of the permittivity and permeabil...
متن کاملMetasurface polarization splitter.
Polarization beam splitters, devices that separate the two orthogonal polarizations of light into different propagation directions, are among the most ubiquitous optical elements. However, traditionally polarization splitters rely on bulky optical materials, while emerging optoelectronic and photonic circuits require compact, chip-scale polarization splitters. Here, we show that a rectangular l...
متن کاملA metasurface carpet cloak for electromagnetic, acoustic and water waves
We propose a single low-profile skin metasurface carpet cloak to hide objects with arbitrary shape and size under three different waves, i.e., electromagnetic (EM) waves, acoustic waves and water waves. We first present a metasurface which can control the local reflection phase of these three waves. By taking advantage of this metasurface, we then design a metasurface carpet cloak which provide...
متن کاملA Multilayer Metasurface Cloak Coating for Monopole Antennas
A multilayer metasurface cloak coating is introduced for monopole antennas. It retains the input impedance and radiation parameters of the antenna for its original operational band. At the same time, it also reduces the monopole’s scattering signature and the received power for the operational band of another system located in close proximity. The coating, consisting of two layers of concentric...
