摘要
Abstract
In practical engineering applications,resonant microarray structures,which typically serve as Frequency Selective Surfaces(FSS),are often required to be deployed on curved substrates.Most of these substrates are non-developable or irregular large-area curved surfaces,and the realization of large-area,damage-free,and conformal fabrication of high-performance FSS on such complex curved surfaces remains a major challenge in curved surface processing.To address this issue,the adoption of electrohydrodynamic jet printing(EHD Jet Printing)technology for the damage-free fabrication of FSS on curved substrates is proposed.For high-precision manufacturing,a set of EHD jet printing experimental devices is developed,and special attention is paid to the regulation of Taylor cone stability—this stability is an essential factor for ensuring continuous and uniform ink ejection during printing.With the support of a simulation system,the correlations between EHD jet printing parameters on curved surfaces,Taylor cone stability,and FSS structural quality are thoroughly analyzed.The results indicate that stable printing on curved substrates can be effectively achieved by maintaining the nozzles equidistant movement along the curved surface and its perpendicular alignment with the substrate.The fabricated band-stop FSS(resonant microarray)exhibits a center frequency of 6.82 GHz,a reflection coefficient of-19.88 dB,and a wave transmission efficiency exceeding 92%in the passband.Moreover,it demonstrates stable filtering performance under varying electromagnetic wave incidence angles and polarization modes,which strongly verifies the feasibility and effectiveness of electrohydrodynamic jet printing technology in the fabrication of FSS on curved surfaces.关键词
