A Non-Decoupled Time-Domain Direct Sampling Method for Inverse Elastic Medium Scattering
Lefu Cai, Hongjie Li, Xianchao Wang
This work is concerned with an inverse medium problem for elastic waves, in which unknown inhomogeneities are reconstructed from time-resolved boundary measurements. We propose a n…
Minnaert resonances and higher-order acoustic modes for bubbles in a viscous fluid with surface tension
Habib Ammari, Xin Fu, Wenjia Jing +1
The aim of this paper is to account for viscosity, surface tension, and interactions between micro-bubbles in approximating their resonant behavior in the ultrasonic regime. Origin…
Mathematical analysis of transverse EM field concentration for adjacent obstacles with nonlocal boundary conditions in the quasistatic regime
Yueguang Hu, Hongjie Li, Hongyu Liu
This paper presents a rigorous mathematical analysis of transverse electromagnetic (EM) field concentration between two adjacent obstacles within the framework of the quasi-static…
A novel time-domain direct sampling approach for inverse scattering problems in acoustics
Yukun Guo, Hongjie Li, Xianchao Wang
This work is concerned with an inverse scattering problem of determining unknown scatterers from time-dependent acoustic measurements. A novel time-domain direct sampling method is…
Elastodynamical resonances and cloaking of negative material structures beyond quasistatic approximation
Hongjie Li, Hongyu Liu, Jun Zou
Given the flexibility of choosing negative elastic parameters, we construct material structures that can induce two resonance phenomena, referred to as the elastodynamical resonanc…
Minnaert resonances for bubbles in soft elastic materials
Hongjie Li, Hongyu Liu, Jun Zou
Minnaert resonance is a well known physical phenomenon and it has many important applications, in particular in the effective realisation of acoustic metamaterials using bubbly med…
