| description | The device for detecting changes in the refractive index of a dielectric medium comprises: at least one metallic layer ready to be placed in contact with the dielectric medium; at least one light source configured to direct transversal magnetic (TM) polarized light towards such metallic layer, so that the light is reflected on such metallic layer; coupling means; and at least one detector configured to receive light reflected by the metallic layer and to detect at least one feature of such light. According to the invention, the metallic layer contains a ferromagnetic material. The invention also relates to a method. |
