  • Method for designing and tuning and system for measuring a refractive index of a magnetic fluid
    Patent number: 6813014
    Abstract: A method for designing and tuning a refractive index of a magnetic fluid is performed by adjusting some characteristic parameters. The characteristic parameters include the type of carrier, the type of magnetic particles, the concentration of the magnetic ingredient; the wavelength of an intended light onto the magnetic fluid layer; the strength of applied magnetic field; the sweep rate of the magnetic field; the direction of the applied magnetic field; the strength of applied magnetic field associated with the thickness of the magnetic fluid layer; and the strength of applied magnetic field associated with the temperature. A magnetic fluid with a designed value of refractive index under zero magnetic field is synthesized by carefully selecting the carrier and the volume concentration of the magnetic particles, and this value can further be tuning around the designed value by changing the forgoing characteristic parameters.
