Electrorotation in graded colloidal suspensions
J. P. Huang, K. W. Yu, G. Q. Gu +1
Biological cells can be treated as composites of graded material inclusions. In addition to biomaterials, graded composites are important in more traditional materials science. In…
Nonlinear ac response of colloidal suspension with an intrinsic dispersion
J. P. Huang, L. Gao, K. W. Yu
When a sinusoidal (ac) field is applied to a suspension containing nonlinear dielectric particles, the electrical response will generally consist of ac fields at frequencies of the…
Theory of ac electrokinetic behavior of spheroidal cell suspensions with an intrinsic dispersion
Lei Gao, J. P. Huang, K. W. Yu
The dielectric dispersion, dielectrophoretic (DEP) and electrorotational (ER) spectra of spheroidal biological cell suspensions with an intrinsic dispersion in the constituent diel…
Ground state of a polydisperse electrorheological solid: Beyond the dipole approximation
H. Sun, K. W. Yu
The ground state of an electrorheological (ER) fluid has been studied based on our recently proposed dipole-induced dipole (DID) model. We obtained an analytic expression of the in…
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…
Dielectric response of spherical particles of graded materials
K. W. Yu, G. Q. Gu, J. P. Huang
We have studied the effective response of composites of spherical particles with a dielectric profile which varies along the radius of the particles. We developed a differential ef…
