Ferrite Tile Application
· Used for EMC chamber
Based on the principle of having complex magnetic permeability equal (or nearly equal) to complex dielectric constant. Materials with this property exhibit an impedance equal to that of "free space" and therefore do not reflect radiated energy at normal incidence. Ferrite Tile can provide 10dB - 25dB of absorption between 30MHz and 1GHz. Tiles are thin (approximately 0.26 inches), but can be heavy (roughly 10 lbs per square foot).
