Abstract :
Reported for the first time are experimental results of surface wave coupling for a Sievenpiper artificial magnetic conductor (AMC) which has an R-Card attached to its surface. The addition of in-plane resistive loss causes the TE surface wave to undergo broadband absorption at frequencies above the normal cutoff frequency of the strictly reactive AMC. Also the TM mode cutoff frequency is reduced with the use of R-card treatments. These two factors create a broader bandwidth for surface wave suppression.
