Abstract
This paper presents an analysis of the magnetic field influence on a planar differential interferometer that uses a magneto-sensitive ferronematic layer. Due to a magnetic field interaction a nematic matrix changes its orientation in a TM mode polarization plane. In consequence, a propagation constant changes only for a TM mode, and a phase difference between TE and TM modes is changed under magnetic field influence. An influence of the optical and geometric parameters of the presented structure on the phase difference of propagating modes is presented.
