Multipole polarizability of a graded spherical particle
L. Dong, J. P. Huang, K. W. Yu +1
We have studied the multipole polarizability of a graded spherical particle in a nonuniform electric field, in which the conductivity can vary radially inside the particle. The mai…
Optical nonlinearity enhancement of graded metal-dielectric composite films
J. P. Huang, L. Dong, K. W. Yu
We have derived the local electric field inside graded metal-dielectric composite films with weak nonlinearity analytically, which further yields the effective linear dielectric co…
Electrokinetic behavior of two touching inhomogeneous biological cells and colloidal particles: Effects of multipolar interactions
J. P. Huang, Mikko Karttunen, K. W. Yu +2
We present a theory to investigate electro-kinetic behavior, namely, electrorotation and dielectrophoresis under alternating current (AC) applied fields for a pair of touching inho…
First-principles approach to dielectric response of graded spherical particles
L. Dong, G. Q. Gu, K. W. Yu
We have studied the effective response of composites of spherical particles each having a dielectric profile which varies along the radius of the particles. We developed a first-pr…
Dielectrophoresis of charged colloidal suspensions
J. P. Huang, Mikko Karttunen, K. W. Yu +1
We present a theoretical study of dielectrophoretic (DEP) crossover spectrum of two polarizable particles under the action of a nonuniform AC electric field. For two approaching pa…
