We consider Faraday rotation by a dilute suspension of small particles embedded in a host. Using the Maxwell-Garnett approximation, we obtain an expression for the complex effective dielectric tensor of the composite in the low concentration limit. The Faraday coefficient becomes anomalously large near the surface plasmon frequency of the small particles. Numerical examples are given for the frequency-dependent off-diagonal part of the dielectric tensor and for the angle of rotation.

    We use a fundamental-measure density functional for hard board-like polydisperse particles, in the restricted-orientation approximation, to explain the phase behaviour of platelet colloidal suspensions studied in recent experiments. In particular, we focus our attention on the behavior of the...

    From Albert Einstein's study (1905) it is known that suspension introduced to a fluid modifies its viscosity. We propose to describe the influence of obstacles on the Stokesian flow as a such modification. Hence, we treat the fluid flow through small obstacles as a flow with suspension. The flow...

    The influence of particles suspended in a fluid on the effective mass density of the suspension is studied. It is shown how at high concentration the low-density, single-particle behavior is modified by retarded hydrodynamic interactions. To simplify the calculation we make a point particle...
