Abstract In this paper, an ultrathin dual-band metamaterial absorber (MMA) is designed. Its top layer consists of two nested split-ring resonators. The calculation result demonstrates that there are two distinct absorption peaks, which are 9.258GHz and 21.336GHz, with absorption rate of 99.78% and 96.91%. It also show polarization-insensitive for normal incident and its thickness is only 1.96% of the wavelength of its lowest absorption frequency. Moreover, we explore the MMA’s absorption mechanism and analyze the influence of main structural parameters on the MMA’s absorption characteristics. The proposed MMA has simple structure and high absorption, it can be applied in electromagnetic stealth, bolometers, sensor and other fields.

In this paper, a new metamaterial absorber which comprises of a symmetrically E shaped split ring resonator patches at the top of the FR4 substrate of height 1.6mm for RF Energy Harvesting is proposed. The proposed design provides two absorption peak one at 5.8GHz with a maximum absorption of about 99% and other at 7.8GHz with a maximum absorption of about 92%. The absorption mechanism is investigated for the proposed metamaterial absorber. Also the polarization behavior of the absorber is also analyzed under various angles of incidence. The absorber has been tuned in such a way to have good broadband response in the UWB range
