Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

Advanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Stochastic dynamics of symmetry reductions to the parabolic nonlinear model in metamaterials

Results in Engineering
The Schrödinger model is investigated in this work using electromagnetic pulse waves in metamaterials with parabolic nonlinearity law. The model is first analysed using Lie symmetry analysis to obtain a better grasp of the system's symmetries and ...

Slow-light and evanescent modes at interfaces in photonic crystal waveguides: optimal extraction from experimental near-field measurements [PDF]

, 2011
We develop a systematic approach for simultaneous extraction of the dispersion relations and profiles of multiple modes in periodic waveguides though a special global optimization procedure applied to near-field electric field measurements in the ...

Metamaterial Transparency Induced by Cooperative Electromagnetic Interactions [PDF]

Physical Review Letters, 2013
We propose a cooperative asymmetry-induced transparency, CAIT, formed by collective excitations in metamaterial arrays of discrete resonators. CAIT can display a sharp transmission resonance even when the constituent resonators individually exhibit broad resonances.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Ultrabroadband Unnaturally High Effective Refractive Index Metamaterials in the Terahertz Region

IEEE Photonics Journal, 2017
We demonstrate that an ultrabroadband, extremely high index of refraction can be realized from the thin window-type terahertz metamaterials composed of strongly multilayer coupled unit cells.

Light coupling in microwave metamaterials

, 2013
We report our recent achievements in tuning metamaterials with light. We introduce a novel approach to design metamaterials with sign-varying nonlinear response. For this purpose, we use split-ring resonators loaded by photodiodes and varactor diodes.
