Abstract
The wide-band absorbance of the absorber made from the well-known metallic dipole patch has been realized by modifying geometrical shape of conventional rectangular bars in single periodic cell. The increase of relative bandwidth of this new absorptive structure with fan-shaped patch can reach and exceed 100% with respect to the centre frequency comparing with conventional dipole patch geometry. The new structure of absorber exciting a new broadband resonant modes results in the bandwidth expanding. The work presented here provides an efficient method to decrease the number of elements and layers of multi-layer metamaterial absorber compared to conventional element structures used previously.
