Abstract

This letter proposes an innovative sandwich frequency selective surface (FSS) that integrates the periodic hollow architecture of aluminum honeycomb with cavity resonance. First, the resonant characteristics of the hollow honeycomb cavities are investigated. A 33% cavity miniaturization can be achieved by converting cavity sidewall boundaries from perfect electric conductor to perfect magnetic conductor (PMC) conditions. Then, a slot structure located at the two boundaries of the honeycomb cavity is introduced to provide slot resonance and act as an equivalent PMC wall to excite the TM_0,2/3,0 mode of the cavity. Finally, a dual-pole bandpass FSS with a center frequency of 7.07 GHz is achieved, featuring a small thickness of 0.059λ₀. The electromagnetic-mechanical properties of aluminum honeycomb-based FSS were fabricated and measured to validate the proposed design strategies. Mechanical tests revealed compressive strength exceeding 2.1 MPa with a density of 0.702 g/cm³, highlighting its lightweight and load-bearing advantages.

基于铝蜂窝腔的带通选频面研究

这封信提出了一种创新的夹层频率选择表面（FSS），它将铝蜂窝的周期性空心结构与腔共振相结合。首先，研究了空心蜂窝腔的谐振特性。通过将腔体边壁边界从完美电导体条件转换为完美磁导体条件，可以实现33%的腔体小型化。然后，在蜂窝腔的两个边界处引入狭缝结构，提供狭缝共振，作为等效的PMC壁，激发腔的TM0、2/3、0模态。最后，实现了中心频率为7.07 GHz的双极带通FSS，厚度仅为0.059λ0。制作并测量了基于铝蜂窝的FSS的电磁力学性能，以验证所提出的设计策略。力学试验表明，抗压强度超过2.1 MPa，密度为0.702 g/cm3，突出了其轻质和承重优势。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
