Using foamed polypropylene (EPP) material, through electromagnetic simulation results, according to the needs of the FREQUENCy application band, the appropriate absorbent is selected to add proportions, which solves the problem of long-term moisture on the traditional absorber material, solves the problem of construction environmental pollution caused by the drop of toner during the construction handling process, and the test results show that the absorption performance of the traditional absorber material can be improved by 3 to 5 dB.
