| چکیده | ||
| The design, simulation, fabrication, and measurement of two structures of metamaterial absorbers (MA) is investigated at microwave frequency in this paper. By stacking of one layer structure on the top of each other, a two-layered structure is generated. The unit cell at each layer consisting of two sets of various circular and square patches are designed so that the structure exhibit quad band absorption response. The advantages of these MAs are being thin, having simple structures, excellent polarization characteristics and maintaining high absorption peaks even at large angles of incidence for both TM and TE polarizations. In addition, measurement of a fabricated prototype shows a satisfactory agreement with the respective simulation results. | ||
