A Novel Approach for RCS Reduction Using a Combination of Artificial Magnetic Conductors
By
Progress In Electromagnetics Research, Vol. 107, 147-159, 2010
Abstract
A thin Artificial Magnetic Conductor (AMC) structure for Radar Cross-Section (RCS) reduction applications is presented. The manufactured prototype, which combines two unit-cell metallization sizes, presenting two resonant frequencies, shows broad AMC operation bandwidth, polarization angle independency, and its angular margin when operating under oblique ncidence is also tested. It is shown that significant RCS reduction can be achieved with the proposed AMCs combination even if a 180º phaseshift between reflected waves is not met. Two designs are considered: the already mentioned design combining AMCs with overlapped frequency bands and the second one combining Perfect Electric Conductor (PEC) and AMC surfaces. A comparison between these two designs regarding RCS reduction, supported by measurements in an anechoic chamber, is presented.
