Abstract
To improve microwave absorption in the X-band frequency range (8.2–12.4 GHz), this work describes the creation and characterization of a new composite material made of graphitic carbon nitride (g-C₃N₄) and strontium hexaferrite (SrFe₁₂O₁₉). Easy manufacturing techniques were used to ensure uniformity and the best possible distribution of both components in the composite. Using the vector network analyzer, microwave absorption characteristics were examined, with reflection loss (RL) serving as the primary performance metric. The composite material exhibited remarkable absorption of microwaves, as evidenced by its considerable reflection loss of −59.22 dB at a thickness of 4 mm. It was discovered that the main factor influencing this improved performance was the synergistic interaction between strontium hexaferrite and graphitic carbon nitride.
期刊介绍:
DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices.
The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
