Thermal-insulating material provided on a metal substrate by means of an EB-PVD process includes a metal having a substantially magnetoplumbitic crystal structure and having a chemical composition according to general formula: Ln3+M2+1+xQ44+A111\u22122xO19. The anchor body has a lower shell and an upper shell. The invention employs low-power communication means, such as ultra wideband, for transfer of data between Tag and Reader, and relatively high power narrowband means to remotely energize the Tag. In a second mode of switching the distribution is changed according to a media-time coding mechanism in which typically data is being transmitted simultaneously across more than one of the multiple diverse medium. A plurality of diaphragm cylinders are provided to one holding head.
