Figure 6. (A) Validation of the electromagnetic attenuation performance with and without PGAA-PTA in the THz region; RCS of PGAA-PTA-0, PGAA-PTA-40 and PEC in (B) X-band and (C) Ku-band; (D) 3D radar-wave scattering patterns of (D₁-D₄) RCS images of PGAA-PTA-0 in X-band, PGAA-PTA-0 in Ku-band, PGAA-PTA-40 in X-band, and PGAA-PTA-40 in Ku-band, respectively; (E) PEC results corresponding to (E₁-E₄) X-band, Ku-band, X-band, and Ku-band, respectively. PGAA-PTA: Polyimide/reduced graphene oxide/AgNW-poly(thioctic acid) aerogel; THz: terahertz; RCS: radar cross-section; PEC: perfect electric conductor; 3D: three-dimensional.
