On the general governing equations of electromagnetic acoustic transducers [PDF]

open access: yes, 2013
In this paper, we present the general governing equations of electrodynamics and continuum mechanics that need to be considered while mathematically modelling the behaviour of electromagnetic acoustic transducers (EMATs).

New Method to Calculate Electrical Forces Acting on a Sphere in an Electrorheological Fluid [PDF]

open access: yes, 2005
We describe a method to calculate the electrical force acting on a sphere in a suspension of dielectric spheres in a host with a different dielectric constant, under the assumption that a spatially uniform electric field is applied.

Acidic magnetorheological finishing of infrared polycrystalline materials

open access: yesApplied Optics, 2016
Chemical-vapor-deposited (CVD) ZnS is an example of a polycrystalline material that is difficult to polish smoothly via the magnetorheological finishing (MRF) technique. When MRF-polished, the internal infrastructure of the material tends to manifest on the surface as millimeter-sized "pebbles," and the surface roughness observed is considerably high ...
