电磁吸波与极化转换融合型超表面设计
Design of metasurface based on combination of electromagnetic absorption and polarization conversion
摘要
Abstract
To suit the application requirements of multi-band absorption of microwave signals and radar communication signal compatibility, a multi-array unit fusion metasurface structure is designed by combining the electromagnetic wave regulation mechanism of absorption and polarization conversion. The electromagnetic absorption and polarization conversion performance of metasurface is simulated by using HFSS electromagnetic simulation software, and its comprehensive regulation mechanism are analyzed. A design method is proposed to add the open-loop polarization conversion metasurface array unit into the cross dipole metasurface unit with resistance loading. The electromagnetic wave absorbing properties of dipole metasurface in low frequency band and the electromagnetic polarization conversion characteristics of open-loop metasurface in high frequency band are integrated by this method. The simulation of the reflectivity of the metasurface structure and the physical image analysis of the surface induced current illustrate the working mechanism of the two metasurface elements in different frequency bands. The results show that the absorption range of the metasurface structure covers the dual bands of 2. 08 ～8. 36 GHz and 13. 32 ～18. 46 GHz, which proves the feasibility of the multi-control mechanism fusion electromagnetic metasurface design method.关键词
