Metal pattern functional layer structure for realizing electromagnetic wave attenuation

The invention discloses a metal pattern functional layer structure for realizing electromagnetic wave attenuation, which can regulate and control the effective dielectric constant and the equivalent magnetic conductivity of a wave-transmitting material by attaching metal patterns which are periodically arranged on the wave-transmitting material, and generates specific response to incident electromagnetic waves. Therefore, the electromagnetic wave transmission performance of the specific frequency band in the specific electromagnetic wave incoming direction is effectively reduced, and the electromagnetic shielding function of the wave-transmitting material is realized. 本发明公开了一种用于实现电磁波衰减的金属图案功能层结构，利用通过在透波材料上附着周期排列的金属图案可以调控透波材料的等效介电常数和等效磁导率，对入射的电磁波产生特定的响应，从而有效减少特定频段特定电磁波来波方向电磁波透射性能，从而实现透波材料电磁屏蔽的功能。
