An equation describing magneto-mechanical vibrations in a rectangular bimorphic element with asymmetric thickness is derived, and an algorithm of its solution in the case of a specimen with free edges is proposed. The modulator is shown to be characterized by a two-dimensional distribution function for the rotation angle of the polarization plane in a light-beam cross-section. Calculations for bismuth-substituted yttrium ferrite garnet on a gadolinium-gallium substrate showed that the rotation angle of the light-beam polarization plane owing to the Faraday effect can reach 3∘ for the fundamental mode of bimorphic element vibrations.</p> ER -
