Absorber and Ferrite Tiles

NTD Shielding Services supply a range of radio wave absorbing materials (RAM) which can be tailored to your specific chamber configuration and specification requirement. Such materials typically take the form of Ferrite Tiles or Pyramidal Absorbers. The key physical attributes of Ferrite within shielding is that it consists of domains with polarised bias and this rotates against the oscillating wave to absorb radiated energy. Ferrites are very good between the frequency range 30MHz to 800MHz with performance diminishing thereafter. All NTD Shielding Services chambers which are to comply with CISPR16-4-1 are fully lined with ferrite tiles to all 6 internal faces
