摘　　要：天线材料在传播过程中受到共振影响造成无线网络的传播波动,而石墨烯纳米材料可以实现共振调节,因此本文研究了石墨烯纳米天线对无线网络的增强作用。结合切比雪夫响应原理,拟定谐振系数优化指标。在明确石墨烯纳米天线结构的基础上,计算石墨烯纳米天线谐振系数,并利用微扰技术分离天线的谐振模式优化该系数。在局域电磁场态密度下,通过局部光激发,完成石墨烯纳米天线对无线网络的增强分析。实验表明:在无线网络误码率较长以及网络时延较高的情况下进行数据传输,石墨烯纳米天线传输质量受网络波动影响较小,证明石墨烯纳米天线谐振系数优化对无线网络存在增强作用。Antenna materials are affected by resonance during the propagation process,resulting in propagation fluctuations in wireless networks.Graphene nanomaterials can achieve resonance regulation,so the enhancement effect of graphene nanomaterials on wireless networks is studied.Based on the corresponding principle of Chebyshev,formulate optimization indicators for resonance coefficient.On the basis of clarifying the structure of graphene nanoantennas,calculate the resonance coefficient of graphene nanoantennas,and optimize the coefficient by using perturbation technology to separate the resonance mode of the antenna.Under the local electromagnetic field density of states,the enhancement analysis of graphene nanoantennas on wireless networks is completed through local light excitation.The experiment shows that when data transmission is carried out in wireless networks with high bit error rates and high network latency,the transmission quality of graphene nanoantennas is less affected by network fluctuations,proving that the optimization of graphene nanoantenna resonance coefficient has an enhancing effect on wireless networks.
