HALL-EFFECT IN 2-DIMENSIONAL COMPOSITES

Conduction in a two-component composite film, subject to a magnetic fi eld, is treated numerically with an interface integral equation method . The composite is chosen to be a square array of starfish-shaped incl usions in an anisotropic matrix. Highly accurate calculations are perf ormed and used to investigate microstructure-independent relations bet ween the effective conductivity tensor elements. Asymptotic studies of closely spaced superconducting and insulating disks in an anisotropic matrix verify theoretical results. All the results in this paper are valid for the analog to the Hall effect in heat conduction, the Righi- Leduc effect.
