摘要/Abstract

摘要：

设计了一种基于钛酸锶钡陶瓷的新型宽带频率选择表面，其基本单元尺度为亚波长，按照三角晶格进行排列。通过调节单元的共振频率，实现了三个共振模式耦合而形成宽带工作的阻带。模拟结果表明，电磁波在0°入射的时候，频率选择表面的带宽为7.8 GHz。当钛酸锶钡陶瓷的相对介电常数由115降低到85时，阻带带宽可以增大到8.7 GHz。该设计具有良好的宽带特性，在电子对抗和隐身领域具有重要的军事价值。

Abstract:

In this paper, a new kind of broad bandstop frequencyselective surface (FSS) based on the highpermittivity barium strontium titanate (BST) ceramic was proposed. The elementary particles of the proposed FSS were subwavelength, and it was arranged in a triangular lattice. By adjusting the resonant frequency of the unit, three resonant modes were coupled to form a stopband. The simulation results showed that when the electromagnetic wave was incident at 0 °, the stopband bandwidth of the FSS could reach 7.8 GHz. When the relative permittivity of barium strontium titanate ceramics was changed from 115 to 85, the bandstop bandwidth could be increased to 8.7 GHz. Therefore, this frequency selective surface based on the barium strontium titanate ceramic with good broadband characteristics has important military value in the field of electronic confrontation and stealth.

Key words: broadband, frequency selective surface, relative permittivity, barium strontium titanate ceramic
