Electromagnetic wave absorbing structure

The invention provides an electromagnetic wave absorbing structure which comprises a surface dielectric array layer, an impedance layer, a dielectric layer and a metal layer from top to bottom, the impedance layer comprises an impedance type frequency selective surface, the impedance type frequency selective surface comprises at least one conducting ring, and the conducting ring is arranged on the dielectric layer. And a plurality of resistors are uniformly distributed in any conducting ring. The electromagnetic wave-absorbing structure can improve the wave-absorbing performance when electromagnetic waves are incident. 本发明提供了一种电磁吸波结构，该电磁吸波结构包括：由上至下的表层介质阵列层、阻抗层、介质层和金属层，其中，所述阻抗层中包括阻抗型频率选择表面，所述阻抗型频率选择表面中包括至少一个导电环，任一导电环中均匀分布有多个电阻。本发明中的电磁吸波结构能够提升电磁波入射时的吸波性能。
