“…Based on the combination of two sets of multiple-order responses (i.e., the 1-oder, 3-oder, and 5-order responses) of the two different sized metallic layers, six-band MPA is realized. The absorption mechanism of six-band MPA is different from previous multiple-band MPAs that only using the overlapping of the single resonance mode (in particular of the 1-order response) of metallic patterns27282934353637383940.…”

This paper reports on a numerical study of the six-band metamaterial absorber composed of two alternating stack of metallic-dielectric layers on top of a continuous metallic plane. Six obvious resonance peaks with high absorption performance (average larger than 99.37%) are realized. The first, third, fifth, and the second, fourth, sixth resonance absorption bands are attributed to the multiple-order responses (i.e., the 1-, 3- and 5-order responses) of the bottom- and top-layer of the structure, respectively, and thus the absorption mechanism of six-band absorber is due to the combination of two sets of the multiple-order resonances of these two layers. Besides, the size changes of the metallic layers have the ability to tune the frequencies of the six-band absorber. Employing the results, we also present a six-band polarization tunable absorber through varying the sizes of the structure in two orthogonal polarization directions. Moreover, nine-band terahertz absorber can be achieved by using a three-layer stacked structure. Simulation results indicate that the absorber possesses nine distinct resonance bands, and average absorptivities of them are larger than 94.03%. The six-band or nine-band absorbers obtained here have potential applications in many optoelectronic and engineering technology areas.

“…So far many methods have been brought up to reduce antenna RCS, such as geometrical shaping [1], [2] and radar absorbing material (RAM) [3][4][5][6][7][8]. In the former case, the antenna can deflect the electromagnetic (EM) waves away from the detective direction, thus reducing RCS in specular directions.…”

“…These absorbers have wide application in communication systems and biomedical such as in radar cross section (RCS) for minimization of aircrafts and submarines protection from electromagnetic interference (EMI). Some effective methods have been proposed to develop Single-Band [7][8], Dual-Band [9][10], Triple-Band [11][12][13] and Broad-Band metamaterial microwave absorbers [14][15], however the design of Quad-Band absorbers with polarization independent within the specified band are difficult [16][17][18]. Hence relatively very small works have been done on QuadBand absorbers [16][17][18].…”

This paper presents a design of Quad-Band polarization independent microwave absorber using metamaterial. Presented absorber is used for C-band as well as for X-band application. The absorptivity level for frequencies 5.0GHz and 7GHz in C-band are 85% and 95% and for frequencies 9.8GHz and 10.8GHz in X-band are 88% and 90%. Such type of absorber could be used in modern communication systems for airborne and surveillance radar signal absorption application.
