This paper is concerned with the analysis of surface polariton resonance for nanoparticles in linear elasticity. With the presence of nanoparticles, we first derive the perturbed displacement field associated to a given elastic source field. It is shown that the leading-order term of the perturbed elastic wave field is determined by the Neumann--Poincaré operator associated to the Lamé system. By analyzing the spectral properties of the aforesaid Neumann--Poincaré operator, we study the polariton resonance for the elastic system. The results may find applications in elastic wave imaging.

弹性体系中纳米粒子的表面极化共振分析

SIAM数学分析杂志,第52卷,第2期,第1786-1805页,2020年1月。
本文涉及线性弹性中纳米粒子的表面极化子共振分析。在存在纳米粒子的情况下,我们首先导出与给定弹性源场关联的扰动位移场。结果表明,扰动弹性波场的超前项由与Lamé系统相关的Neumann-Poincaré算子确定。通过分析上述Neumann-Poincaré算子的光谱特性,我们研究了弹性系统的极化子共振。该结果可在弹性波成像中找到应用。
