The periodic arrangement in metamaterial (MM) should be maintained to ensure the extraordinary properties, but how much periodic irregularity is allowed generally without degrading the properties is not only important for the tolerance in fabrication but interesting scientifically. We introduce the wrecked effect in MM utilizing perfect MM absorber in visible and GHz ranges. The original perfect MM properties turn out to be maintained until MM is destroyed to 10%. In the view of MM absorber, even 40% broken meta-pattern are still good for absorption higher than 93%, the criterion for perfect absorption. The wrecked pattern over 80% result in absorption of nearly 50% in both simulation and experiment, which is even higher than expected. These results can lead to broad applications at the present and in near future through more convenient and cost-effective research and development on MMs.

超材料可接受的损坏超模式水平

应保持超材料（MM）中的周期性排列以确保非凡的性能，但在不降低性能的情况下，通常允许多少周期性不规则不仅对制造公差很重要，而且在科学上也很有趣。我们在可见光和 GHz 范围内利用完美的 MM 吸收器介绍了 MM 中的破坏效应。原来完美的 MM 属性会一直保持到 MM 被破坏到 10%。在MM吸收体看来，即使是40%的破碎元模式，仍然可以达到93%以上的吸收，这是完美吸收的标准。在模拟和实验中，超过 80% 的破坏模式导致吸收接近 50%，这甚至高于预期。
