Camouflage detectors that can detect incoming radiation from any angle without being detected are extremely important in stealth, guided missile, and heat-seeking missile industries. In order to accomplish this, the absorption emission processes must be manipulated simultaneously. However, Kirchhoff's fundamental law suggests always same direction

The narrowband meta-absorbers exhibit significantly enhanced electromagnetic confinement capabilities, showcasing broad application prospects in sensing fields. They can be applied for biomarker detection, chemical composition analysis, and monitoring of specific gas the environment. In this work, we propose a 3D meta-absorber with an out-of-plane plasma mechanism based on two-photon printing system. Compared to conventional fabrication metal-insulator-metal 2D meta-absorber, absorber is composed metal layer resin from top bottom; its manufacturing process simpler, only including magnetron sputtering deposition. A noticeable absorbing resonance appears at 0.3142 THz perfect absorbance high Q -factor 104.67. theoretical sensitivity refractive index sensor reaches up 172.5 GHz/RIU, figure merit (FOM) 19.56. experiments, it was validated as doxycycline (DCH). As DCH concentration increases 0 4 mg/mL, absorption intensity decreases around 49%, while resonant frequency shift 70 GHz. It reflects real-time residual content DCH, potentially trace antibiotic detection. results showcase capability strong terahertz spectrum, along high- characteristics DCH. metamaterials, diversity metamaterial expands, introduces additional effects provide greater flexibility manipulating waves. device offers opportunities biochemical sensing.
