Abstract

The icing will affect the characteristics of the radome with “High penetration in the band, strong stealth out of band”. Most of the existing research is on the electromagnetic properties calculation of frequency selective surface (FSS) in ideal environments, and there is a lack of research on the electromagnetic properties calculation in icing environment. In this paper, a new algorithm is proposed, and taking icing monopole FSS as the research object, the hybrid algorithm is verified, which has the advantages of improving the calculation speed and accuracy. On this basis, the influence of icing, icing thickness and ε(ε) of the ice layer on the wave-transmitting characteristics of FSS is analyzed. The calculation results show that: Icing will make the resonant frequency of FSS smaller; and as the icing thickness increases, the number of frequency resonance points increases; as the ε of the ice layer increases, the resonant frequency of the FSS decreases. It can provide an important theoretical basis for the application of FSS in the icing environment.
