Abstract

Abstract In this paper, a quad-band polarization- and incident-angle independent low-profile metamaterial absorber is proposed. The design consists of three square rings one into another and one plus-shaped slot structure. The size of the unit cell is 11 × 11 mm2 and is printed on an FR-4 substrate having a thickness of 1 mm. It provides 99.2%, 97.6%, 99.3%, and 99.9% absorption at 3.55 GHz, 5.27 GHz, 7.57 GHz, and 11.57 GHz, respectively, thus covering the S, C, and X bands. The surface current distribution of the proposed absorber is also shown at the four resonating frequencies to get a better insight into the design. Moreover, the stability of the proposed design is also validated with different incident angles (for both TE and TM modes) and polarization angles. In addition, a prototype of the proposed absorber structure is also fabricated and then verified experimentally.

四波段偏振与入射角无关的低轮廓超材料吸收体分析

摘要本文提出了一种四波段偏振和入射角无关的低剖面超材料吸收体。该设计由三个方形环和一个加号槽结构组成。晶胞的尺寸为11×11mm2，印刷在厚度为1mm的FR-4基板上。它在3.55GHz、5.27GHz、7.57GHz和11.57GHz下分别提供99.2%、97.6%、99.3%和99.9%的吸收，从而覆盖S、C和X波段。还显示了所提出的吸收器在四个谐振频率下的表面电流分布，以更好地了解设计。此外，还验证了所提出的设计在不同入射角（TE和TM模式）和偏振角下的稳定性。此外，还制作了所提出的吸收器结构的原型，并进行了实验验证。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
