Nonlinear alternating current responses of electrorheological solids.
When a composite containing nonlinear dielectric particles suspended in a host medium is subjected to a sinusoidal alternating current (ac) electric field, the dielectric response of the composite will generally consist of ac fields at frequencies of higher order harmonics. For an electrorheological (ER) solid under structure transformations due to external fields, we apply the Ewald-Kornfeld f...
متن کاملNonlinear alternating current responses of dipolar fluids.
The frequency-dependent nonlinear dielectric increment of dipolar fluids in nonpolar fluids is often measured by using a stationary relaxation method in which two electric fields are used: The static direct current (dc) field of high strength causing the dielectric nonlinearity, and the probing alternating current (ac) field of low strength and high frequency. When a nonlinear composite is subj...
متن کاملNonlinear alternating current responses of graded materials.
When a composite of nonlinear particles suspended in a host medium is subjected to a sinusoidal electric field, the electrical response in the composite will generally consist of alternating current (ac) fields at frequencies of higher-order harmonics. The situation becomes more interesting when the suspended particles are graded, with a spatial variation in the dielectric properties. The local...
متن کاملAC electrokinetics of the microparticles in electrorheological solids
Under the application of electric fields, the structure of electrorheological (ER) solids can be changed from the body-centered tetragonal lattice (ground state) to other lattices. For a particle in the lattice, we derive its dipole factor by taking into account both the local-field effect arising from all the other particles and the multipolar interaction between two touching particles, throug...
متن کاملInterparticle Force in Nonlinear Electrorheological Fluids
The prediction of the strength of the electrorheological (ER) effect is the main concern in a theoretical investigation of ER fluids. The ER effect originates from the induced interaction between the polarized particles in an ER fluid. As the mismatch in material parameters (either conductivities or dielectric constants) is responsible for the ER effects, previous theoretical studies have taken...
