Dajun Zhang, a doctoral student at the University of Wisconsin-Madison, presents his work on developing a metamaterial for underwater acoustic manipulation on Tuesday, May 20, at 3:20 p.m. CT as part ...

But there's a trade-off: The stiffer a material, the less flexible it is. MIT engineers have now found a way to fabricate a metamaterial that is both strong and stretchy. The base material is ...

Relaxation model is absent in metamaterial research. Polarization is one of the most important electromagnetic (EM) properties of dielectric materials. The essence of polarization is electron ...

Abstract: The multi-layer metamaterial absorbers (MMAs) are designed by using Kriging surrogate model. By selecting different metamaterial models from the metamaterial database, metamaterial absorbers ...

In this work, a theoretical model for the transmittance in a left-handed metamaterial of different geometries is presented. The proposed unit cells are a combination of conducting wires of rectangular ...

First, the governing equations of elastic wave propagation in cylindrical shell structures are derived through coordinate transformation. Subsequently, numerical models of the metamaterial cylindrical ...

The metamaterial changes its constitutive response concurrently as the phase transitions ... Importantly, we introduce a Landau free energy framework to model the phase transitions for the ...

Exhaustive research on single-beam metamaterial vibration attenuation structures using local resonators exists in literature. Moreover, there are recent attempts at modelling double-layered beams with ...

Camera lenses could be going on a substantial diet, thanks to a new “metamaterial lens” developed by a team at Harvard University. Federico Capasso, a professor of applied physics and ...

where the metamaterial has near-zero density near the dipole resonance, the experiment investigated the ball hanging from a thread in a standing wave tube. Here, too, they observed blocking of sound ...
