Transformation-Invariant Metamaterials [PDF]

Physical Review Letters, 2019
The fundamental semiconductor concept of doping has recently been transplanted to photonics in the platform of epsilon-near-zero (ENZ) media. By doping nonmagnetic impurities, ENZ media can exhibit almost arbitrary magnetism. However, this original photonic doping approach results only in isotropic media and thus cannot achieve impedance matching for ...

Method for extracting the surface impedance of a generic reflective metasurface

Scientific Reports
We develop a method for the extraction of the surface impedance tensor of a generic reflective metasurface using an analytic relation between the tensorial surface impedance and the four polarisation-dependent reflection coefficients.

SAR Reduction Using Integration of PIFA and AMC Structure for Pentaband Mobile Terminals

International Journal of Antennas and Propagation, 2017
In this paper, a capacitive grating artificial magnetic conductor (AMC) is presented to reduce the specific absorption rate (SAR) in pentaband mobile terminals. The AMC structure is implemented using a dielectric film with the printed arrays of the metal

A Toroidal Metamaterial Switch [PDF]

Advanced Materials, 2017
AbstractToroidal dipole is a localized electromagnetic excitation that plays an important role in determining the fundamental properties of matter due to its unique potential to excite nearly nonradiating charge–current configuration. Toroidal dipoles are recently discovered in metamaterial systems where it is shown that these dipoles manifest as ...

Beaded metamaterials

Nature Communications
From the pragmatic to the symbolic, textiles play a prominent role in some of the most demanding yet ubiquitous scenarios, such as covering the complex and dynamic geometries of the human body. Textiles are made by repeated manipulations of slender fibers into structures with emergent properties. Today, these ancient metamaterials are being examined in
