Abstract
A lightweight, low-thickness, durable, and reliable multi-band radar stealth-bulletproof integrated metamaterial includes a ceramic layer, an ultrahigh molecular weight polyethylene (UHMWPE) fiber composite bulletproof layer, a graphene-based metamaterial filter layer, an UHMWPE fiber composite attenuation layer, and a carbon fiber composite reflective layer stacked in sequence. The two UHMWPE fiber composite layers are configured to attenuate radar waves. The circuit resonance of the graphene-based metamaterial filter layer is configured to generate a passband and a stopband simultaneously. The bulletproof layer and the attenuation layer are controlled by the graphene-based metamaterial filter layer in terms of working conditions in different radar frequency bands to establish a structure capable of generating λ/4 resonance at both low and high frequencies, so as to arrive at a stealth-bulletproof integrated metamaterial with small thickness and excellent dual-band radar wave absorption capability.
