摘要

本研究提出了一种用于微波应用的超材料吸收体(MMA)。所设计的超材料在27.5 GHz和31 GHz谐振频率下均具有99.99%的吸收率。分别覆盖27.325-27.705 GHz和29.505 -31.264 GHz两个0.38 GHz和1.76 GHz 90%的吸收带宽。研究了吸收、电场、磁场和表面电流分布，了解了双波段吸收行为的物理机制。此外，为了更好地理解超材料的吸收特性，还对不同偏振角的MMA进行了分析，并研究了尺寸对其吸收特性的影响。

Dual-band Metamaterial Absorber for Ka-Band Satellite Application

In this study, a Metamaterial Absorber (MMA) has been proposed for microwave applications. The designed metamaterial exhibits 99.99% of absorption at both 27.5 GHz and 31 GHz resonance frequency. Which covers two 0.38 GHz and 1.76 GHz 90% absorption bandwidth from 27.325-27.705 GHz and 29.505G-31.264 GHz respectively. The absorption, electric field, magnetic field, and surface current distribution have been presented to understand the physical mechanism of the dual-band absorption behavior. Furthermore, the MMA is analyzed with different polarization angles and the effect of the size has been studied for a better understanding of the metamaterial absorption characteristics.
