Application of electrically controlled interference for observing the autowave process in the near-electrode layer of a magnetic fluid and in an electrically tunable color filter

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
