Oak wood and co-precipitation chemical interactions
−64.26 dB at 14.36 GHz
By co-precipitation chemical interactions for magnetic wood synthesis process and by hand lay-up method, the best results of RL are obtained at 10.2 GHz of −9.40 dB.
Wood and (1) coating type (Ni–Zn ferrite powder coated onto a fibre board), (2) powder type (Ni–Zn ferrite powder and cider wood powder mixed and pressed into boards), (3) impregnated type (cider wood impregnated with a water-based magnetic fluid), (4) sandwich type (combination structure consisting of a fibre board layer/magnetic binder layer/fibre board layer).
At 1.93 GHz, the RL as −16.69 dB, −13.83 dB, −3.64 dB.
