Carbon microspheres (CMSs) are recognized as highly effective microwave absorbers due to their exceptional wave absorption properties. In this study, 5,10,15,20-tetrakis(4-aminophenyl)porphyrin, a metamaterial, was chemically bonded CMSs─considered conjugated carbon structure─using 1,3-dibromopropane linker explore the synergistic properties and capabilities of synthesized composite. The structures were characterized by using X-ray diffraction, FE-SEM, Fourier transform infrared, diffuse reflectance spectroscopy, VNA analyses. Remarkably, gene-modified absorber demonstrated maximum reflection loss −105.58 dB at 22.93 GHz, with an ultrathin thickness only 0.50 mm. When architected samples blended poly(methyl methacrylate), practical polymer, they exhibited broad efficient bandwidth across entire K-band, coupled moderate shielding effectiveness, making them ideal for mitigating electromagnetic pollution in everyday life. This study offers inspiration researchers fabricate design new enhanced range applications.
