摘要：

In this article, an ultrathin Radar Absorbing Material (RAM) based on high-impedance surfaces (HIS) has been investigated. Simple analytical formulas for the input impedance of HIS RAM are present and the equivalent model of lumped resistor is given to achieve better absorbing performance. From the simulated results, it is seen that the absorbing band of HIS RAM is decided by the reflection phase of HIS in the range +/- 60 degrees, the measured absorbing frequency band moved toward lower-frequency than the simulated results, which attribute to the parasitic capacitance introduced by lumped resistors.
