| Abstract: | The radar absorption coating generated by natural spine-ferrite (iron sand) and polyurethane has two absorption peaks between 7GHz and 12GHz. The reflectivity is between 5. 2dB and 8. 5dB when the thickness is 1. 25mm. Having the radar absorption coating (iron sand) as basic material, and adding spine-ferrite,paramagnetic, rare-earth and hexagonal ferrite to it, we can generate a composite radar absorption coating,the reflectivity can reach 18dB-25dB. The matching thickness is 1. 1-1. 2mm. The distance between two absorption peaks>4. 4GHz. The process is simple and the price is low. |
