Based on the theory of impedance matching, a multilayer absorbing material with the "pitfall" structure was designed. The multilayer absorbing material with 5 layers was obtained by optimization of the schemes, and the material shows 2 absorbing peaks in the broadband of 2~18 GHz frequencies. The peak in high frequencies can be adjusted with no effect on the peak in low frequencies through changing the thickness of the fifth layer. The changes of input impedances were displayed by analyzing the impedance chart. The prepared multilayer absorbing material was named JB-5, which processes the reflectivity no more than -12 dB in 6~17 GHz with the thickness no more than 5 mm and a good performance of standing the environment. The absorbing material can be produced in laboratory and pasted on surfaces of target with special adhesive by trimmed into required shapes so as to reduce the reflection of electromagnetic waves effectively.
