Study on the Scattering Properties of an Artificial Electromagnetic Hard Surface
An artificial electromagnetic hard surface realized by the longitudinally oriented metal strips loaded on a grounded dielectric substrate is proposed.Electromagnetic scattering properties of the proposed structure are analyzed for both transverse magnetic(TM)polarization and transverse electric(TE)polarization,where TM polarization is defined by the polarized direction of the incidence electric field E parallel with the metal strips.The scattering properties of a high impedance surface(HIS)with similar structure are also proposed for comparison.In the case of the HIS,radar cross section(RCS)reduction over broad angles can be obtained for TE polarization,but get worse for TM polarization.While in the case of the hard surface,RCS reduction at the whole considered angles can be obtained for TE polarization,and almost invariable for TM polarization,which has the potential advantages in antenna design and stealth technique.To explain this phenomenon,the bistatic RCS are also analyzed.And the scattering reduction is estimated by comparing the mono-and bistatic scattering patterns of the hard surface loaded and unloaded metal cube.
