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.
