“…Aimed at a working frequency in X-band region and in particular from 9.5 to 10GHz, the device was designed and manufactured in Arlon material. Arlon fiberglass laminate for microwave application is typically used for the fabrication of antennas [21], and recently proved to represent a good choice as a metamaterial substrate [22]. Finally, its compatibility with the standard micro-fabrication techniques is well suited for an inexpensive metamaterial prototype.…”

In this article, we present a metamaterial absorber (MMA), and more specifically a metasurface based on a periodic structure consisting of double split-ring resonators (dSRR) which efficiently absorbs electromagnetic radiation for a wide range of incidence angles for both the transverse electric (TE) and the transverse magnetic (TM) polarizations. The proposed unit cell was designed employing a full 3-D electromagnetic solver based on the Finite Element Method (FEM). The unit cell consists of a square splitring resonator and a thin metallic plate separated by a dielectric layer. Investigations of parameterization and optimization have shown that small modifications in the geometry of the resonator led to enhanced angular absorption. The numerical simulation stage was followed by design and fabrication of a prototype containing several unit cells. The measurements on the prototype show an absorbance peak larger than 84% and 58% for the incidence angles θ=0˚ and θ=70˚ respectively, at 9.73 GHz. The proposed MMA and its variations enable numerous applications such as defense systems, communication and stealth technologies.
