Electromagnetic Emergence in Metamaterials [PDF]

, 2002
This chapter focuses on the emergent electromagnetic properties in such heterogeneous materials that are, in today’s discussion, being more and more often called “metamaterials.” More precisely, the very concept of metamaterial is under study as also are the preconditions under which such a term is appropriate.

A Compact Resistively Loaded Metamaterial Absorber for 2.4 GHz RF Energy Harvesting With Impedance‐Matched Rectifier Analysis

Advanced Electronic Materials, EarlyView.
A compact resistively loaded metamaterial absorber captures RF energy at 2.4 GHz and directs most of the accepted power to modeled loads. The resonant response is confirmed experimentally for the fabricated absorber, while an impedance‐matched rectifier is evaluated through simulation. The stage‐wise results distinguish absorber, rectifier, and cascade

Broadband Near‐Field Computational Microwave Imaging Enabled by Nonperiodic Dispersive Unit‐Cell Loading in a Passive Metasurface

Advanced Electronic Materials, EarlyView.
A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish

A Magnetically Programmable Metasurface for Versatile Scattering Manipulation in the Microwave Band

Advanced Electronic Materials, EarlyView.
A magnetically programmable metasurface converts external magnetic fields into microwave phase modulation, thereby removing surface bias wiring. This mechanism achieves both retro‐reflective beam control and radar scattering suppression, offering a contactless, barrier‐penetrating solution for on‐demand electromagnetic scattering reconfiguration ...
