The creation of a FAR using ferrite tiles works using a resonant system with ferrite tiles. The resonant frequency is dependent on the thickness of the tiles. At this frequency the damping is maximized and approx rising at 6 dB/oct . Standard tiles resonate at 130-150 Mhz. Has anyone of you experimented with multiple thickness ferrite tiles in a room, thus spreading out the dip in the curve over a larger frequency ? I was thinking of mixing thinner tiles for high frequencies with the standards ones to give up some of the damping around 150 Mhz and to improve the characteristics at higher frequencies.
I also am looking for a supplier for 100x 100 mm ferrite tiles. Apart from the well known and easy solutions, I need to look for alternatives also. If anyone of you has a stockpile of tiles available (surplus or for sale), let me know in private.
