Wideband thin resistive metamaterial radar absorbing screen

It has been demonstrated that two layer metamaterial Hilbert curve array constructed from low conductivity material can act as a thin wideband radar absorbing screen. The advantage of using Hilbert curve over traditional circuit analogue radar absorbing screen is the smaller unit cell size, resulting in reduced coupling to higher order Floquent modes and reduced diffraction effects, which in turn reduces reflection at oblique angles of incidence. The low conductivity Hilbert curve array gives much wider bandwidth than conductive space filling curve based absorbing screen. Furthermore the structure is simpler than a typical circuit analogue radar absorbing screen.
