In this study, the electromagnetic (EM) performance of talc/NiTiO3 composite was evaluated. The morphology of talc displayed a lamella structure; there were many nanoparticles of NiTiO3 coated on the talc lamella. Thermal destruction occurred, which increased the surface area from 2.51 m2 g-1 to 79.09 m2 g-1 at the calcined stage at 650°C. The presence of NiTiO3 increased dielectric loss and ma...

In this paper, we proposed a high-performance electromagnetic-wave metamaterial absorber which can be used directly for 5G technology. The exhibits high performance in tailored frequency range of 28 ± 1 GHz. At both transverse-electric and transverse-magnetic polarization, the absorption exceeds 99% when electromagnetic wave is incident normally, keeps being over 97% as angle increases even to ...

With the proliferation of use wireless communication technologies, lightweight, easily fabricated electromagnetic wave (EMW) absorbers are in great demand for commercial and stealth applications. In this paper, well-defined Cu2O microcubes were successfully converted into S-doped Cu2-xSe micro-cubic boxes at room temperature by a template-directed situ selenization/sulfidation reaction. The obt...
