  • [PP2-2-7-5] Orientation polarisation of media
    All bi- or multi-polar (non-inert) media have the tendency to orient themselves in 3D-space if an external non-ionizing electro-magnetic field is excited on them. This orientation polarization is caused by negatively and positively charged areas within the media, for instance due to charges of the different molecules and atoms building up the media, under the premise that the media is able to rotate (partly) freely and is not completely fixed. Molecules of liquid water are a prime example. Here the two positively charged hydrogen atoms are oriented in a 105-degree configuration to the negatively charged oxygen atom, forming a slightly charged bi-polar medium that orients itself under electromagnetic radiation treatment, especially at the frequency range of microwaves and millimeter-waves.
