论文摘要
使用光谱域方法分析了嵌入在平面分层单轴培养基中的任意形状的各向异性和空间分散石墨烯斑块。提出了使用Rao-Wilton-Glisson子域基函数的光谱域方法的配方和计算方法，并提出了将石墨烯表面电导率张量的全波形向量Bhatnagar-krook配方合并。阻抗矩阵通过一种新型的数值方法有效地评估，该方法首先用Chebyshev多项式近似光谱域绿色函数，基础函数和电导率张量，然后总和到傅立叶变换的系数。在所证明的各种结构中观察到了由于空间色散引起的谐振频率和当前分布的变化。
Anisotropic and spatially dispersive graphene patches of arbitrary shape embedded in planarly layered uniaxial media are analyzed using spectral-domain method of moments. Formulation and computational methods for the spectral-domain method of moments using the Rao-Wilton-Glisson subdomain basis function and incorporating the full-wavevector Bhatnagar-Gross-Krook formulation of graphene surface conductivity tensor are proposed. The impedance matrix is efficiently evaluated by a novel numerical method which firstly approximates the spectral-domain Green function, basis function and conductivity tensor with Chebyshev polynomials, and then sums up the Fourier transformed coefficients. Blue-shift of the resonant frequency and variation of the current distribution due to spatial dispersion are observed in various structures demonstrated.
