The present invention relates to modulation elements for electromagnetic radiation and to modulation devices and systems comprising these devices, such as e.g. television screens and computer monitors, as well as to micrometer wave components. The modulation elements according to the invention comprise a mesogenic modulation medium with a dielectric anisotropy, which shows two or more distinct transitions upon application of an electric field. The mesogenic modulation media used in the modulation elements for electromagnetic radiation are also a subject of the present invention.

Modulation element comprising a mesogenic modulation medium having a cybotactic nematic phase that shows two distinct electro-optical transitions at one single temperature
