AI Technical Summary
Existing stealth cloak technology is limited by bandwidth and cannot achieve broadband coverage; furthermore, stealth cloaks based on resonant units are easily detected with precision.
A four-layer composite microstructure with superdispersive broadband stealth features is designed, comprising a gold structural ground layer and an isotropic square ring structure layer, with polyimide as the dielectric layer. The microstructure satisfies the phase dispersion relation of the causal law, thereby achieving broadband stealth.
It achieves THz ultra-wideband full polarization stealth, and the ultra-thin stealth cloak effectively camouflages itself in complex environments, promoting the practical application of electromagnetic stealth cloaks and possessing significant military application value.
