The effective operation of certain electronic, medical, industrial, and testing equipment relies
on high-quality focusing and imaging capability, which also plays a vital role in the field of …

We present an analytical framework to investigate the acoustic performance of an array of
closely spaced spherical cavities embedded in a thin soft medium submerged in water. Each …

Multi-layer structures possess highly geometrically tunable optical resonances to change the
surface plasmon frequencies in the wide range. A simple analytic model is presented to …

The aim of this paper is to provide a mathematical theory for understanding the mechanism
behind the double-negative refractive index phenomenon in bubbly fluids. The design of …

Minnaert resonance is a widely known acoustic phenomenon, and it has many important
applications, in particular in the effective realization of acoustic metamaterials using bubbly …

The ability to manipulate the propagation of waves on subwavelength scales is important for
many different physical applications. In this paper, we consider a honeycomb-lattice of …

Robustly manipulating waves on subwavelength scales can be achieved by, first, designing
a structure with a subwavelength band gap and, second, introducing a defect so that …

This article provides a rigorous mathematical analysis of acoustic wave scattering induced
by a high-contrast subwavelength resonator whose material density is periodically …

This paper provides several contributions to the mathematical analysis of subwavelength
resonances in a high‐contrast medium containing NN acoustic obstacles. Our approach is …

In the recent years, we witness a great interest in imaging, in a wide sense, using contrast
agents. One of the reasons is that many imaging modalities, as the ones related to medical …
