Abstract
This paper presents a metamaterial absorber unit sell structure with four-element electric-LC resonators (ELC). In order to enhance the operating bandwidth of the proposed absorber unit cell two pairs of ELC resonators with a different size are used. The proposed unit cell shows negative permittivity and permeability when the electric field is parallel to the capacitive gap and the magnetic field is normal to the plane of ELC resonator. The simulated results show peak absorbance over 90% at two frequencies of 8.53 and 9.08 GHz, respectively.
