Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

Advanced Materials Technologies, EarlyView.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Performance of limestone‐based sorbent for sorption‐enhanced gasification in dual interconnected fluidized bed reactors

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract A possibility to carry out sorption‐enhanced gasification (SEG) is represented by its integration with the calcium looping concept in dual interconnected fluidized beds (DIFB). This article is focused on the sorbent CO2 uptake performance and attrition/fragmentation tendency when operating conditions simulating those of a DIFB‐SEG process are ...

Few Photons Probe Third‐Order Nonlinear Properties of Nanomaterials in a Plasmonic Nanocavity

Advanced Optical Materials, EarlyView.
It is demonstrated that a few photons probe the nonlinear optical properties of different nanomaterials inside a plasmonic nanocavity. A simple analytical model fits the experimental result, which shows a strong dependence on the nanocavity resonance.

Homogenization of the Poisson equation in a non-periodically perforated domain [PDF]

arXiv, 2019
We study the Poisson equation in a perforated domain with homogeneous Dirichlet boundary conditions. The size of the perforations is denoted by $\epsilon$ > 0, and is proportional to the distance between neighbouring perforations. In the periodic case, the homogenized problem (obtained in the limit $\epsilon$ $\rightarrow$ 0) is well understood (see ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, EarlyView.
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

Random homogenization of p-Laplacian with obstacles in perforated domain [PDF]

arXiv, 2010
In this paper,we will study the homogenization of $p$-Laplacian with obstacles in perforated domain, where the holes are periodically distributed and have random size. And we also assume that the $p$-capacity of each hole is stationary ergodic.
