成簇活细胞的线性介电响应
Linear dielectric response of clustered living cells
摘要：
利用光谱方法分析了由紧密连接的两个或多个活细胞组成的线性簇的介电行为。该系统的极化率作为线性响应算子的本征模的展开而获得，显示出几何参数与电参数的明显分离。具有第二大本征值的本征模在粒子之间的结变紧时占主导地位，但仅当所施加的场与簇轴对齐时。这种效应解释了一个独特的低频弛豫中观察到的线性集群的悬浮液的阻抗谱。
英文摘要：
The dielectric behavior of a linear cluster of two or more living cells connected by tight junctions is analyzed using a spectral method. The polarizability of this system is obtained as an expansion over the eigenmodes of the linear response operator, showing a clear separation of geometry from electric parameters. The eigenmode with the second largest eigenvalue dominates the expansion as the junction between particles tightens, but only when the applied field is aligned with the cluster axis. This effect explains a distinct low-frequency relaxation observed in the impedance spectrum of a suspension of linear clusters.
