Abstract

A novel microwave metamaterial absorber design is introduced along with its manufacturing and characterization. Significant results considering both bandwidth and angular stability are achieved. Parametric analysis and simplified equivalent circuit are provided to give an insight on the key elements influencing the absorber performance. In addition, the constitutive parameters of the effective medium model are obtained and related to the absorber resonant behavior. Moreover, a new thinner and more flexible absorber version, preserving broad bandwidth and angular insensitive performance, is simulated, and an 8 × 8 unit-cells prototype is manufactured and measured for a limited angular margin in an anechoic chamber.

摘要

介绍了一种新型微波超材料吸收体的设计及其制造和表征。在带宽和角度稳定性方面都取得了显著成果。提供了参数分析和简化的等效电路，以深入了解影响吸收体性能的关键因素。此外，还获得了有效介质模型的本构参数，并将其与吸收体的共振行为相关联。此外，还模拟了一种新的更薄、更灵活的吸收体版本，该版本保留了宽带宽和角度不敏感性能，并制造了一个8×8单元的原型，在消声室中对有限的角度范围进行了测量。
