Abstract

The use of electrically controlled interference—changes in the spectrum (intensity) of light reflected from a two-layer structure with variable thickness (conductive ITO coating—a layer of magnetite particles)—is described in an electric field to visualize and observe the autowave process in the near-electrode layer of a magnetic fluid. Application of electrically controlled interference in an electrically tunable color filter is demonstrated.
