Abstract:

A novel radar reflection screen composed of the polarization-dependent mutiband artificial magnetic conductor (PDMAMC) and perfect electric conductor cells is proposed. The PDMAMC is realized by etching a complementary split ring resonator (CSRR) on the patch of a conventional artificial magnetic conductor. Around the two/three operational frequencies of the PDMAMC-elements for different electric field polarizations, the reflection of the PDMAMC and perfect electric conductor have opposite phases, so for any normal incident plane wave the reflections cancel out. The basic principle is discussed and a sample is measured. The results show that the proposed method is feasible and effective for polarization-dependent mutiband RCS reduction.

Key words: artificial magnetic conductor, reflection screen, polarization-dependent, mutiband, radar cross section reduction
