Abstract
In this paper, a split ring-slot structure-based metamaterial absorber is introduced and investigated numerically and experimentally for horizontal and vertical configurations from 1 GHz to 9 GHz. The absorption performance is determined from the scattering parameters obtained numerically using CST Microwave Studio. A comprehensive verification is done experimentally by free space measurement using Vivaldi horn antennas with vector network analyser. The experimental absorption spectra are in agreement with the simulated ones. For horizontal configuration, the structure possesses dual-band absorption. The experimental measurement result indicates that the metamaterial absorber achieves high absorption of 84.3 % at 6.24 GHz. The absorber in vertical configuration shows absorption at higher frequency, which is 92.4 % at 8.4 GHz
