Study of Light Polarization by Ferrofluid Film Using Jones Calculus

We studied the polarized light patterns obtained using a thin film of ferrofluid subjected to an applied magnetic field. with field configurations between parallel plates, monopolar, tetrapolar, and hexapolar, how varies for different intensities orientations Using Jones calculus, we explored key optical properties this system these relate have observed general aspects by transmission in Ferrocell polariscopes analyzing resulting vector, such as formation rotation dark bands known isogyres. suggest that Ferrocell, two effects occur. The primary effect is dichroism, which more sensitive component direction plane. secondary birefringence can be circular polarization light. Birefringence related thickness ferrofluid.
