摘要

为了改善 X 波段频率范围（8.2-12.4 GHz）的微波吸收，这项研究描述了一种由石墨氮化碳（g-C₃N₄）和六铁锶（SrFe₁₂O₁₉）制成的新型复合材料的制作和特性分析。为确保两种成分在复合材料中的均匀性和最佳分布，采用了简便的制造技术。使用矢量网络分析仪检测了微波吸收特性，主要性能指标为反射损耗（RL）。复合材料对微波的吸收效果显著，在厚度为 4 毫米时，其反射损耗高达 -59.22 dB。研究发现，影响这种性能改善的主要因素是六价铁锶和氮化石墨碳之间的协同作用。

Study of microwave absorption properties of strontium hexaferrite (SrFe12O19) and graphitic‑carbon nitride (g-C3N4) composite in X-band range

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 (R_L) 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.
