Abstract

Computational algorithm for determining the descriptor of autonomous blocks with virtual Floquet channels (MFABs) containing magnetically functionalized carbon nanotubes (MFCNTs) with encapsulated magnetic nanoparticles is developed. The algorithm is based on solving the 3D problem of diffraction for the Maxwell’s equations together with the Landau–Lifshitz equation by applying the Galerkin projection method. Electrodynamic calculation of the complex wavenumbers of the longitudinal and transverse waves propagating in the 3D MFCNT arrays as functions of magnitude of the bias field in the millimeter and terahertz frequency ranges is carried out based on the characteristic equation by means of the developed computational algorithm for calculation of the MFAB conductivity matrix.

微波和太赫兹电磁辐射与磁功能化碳纳米管三维阵列共振相互作用的数学建模
摘要 开发了一种计算算法,用于确定具有虚拟 Floquet 通道 (MFAB) 的自主块的描述符,该自主块含有封装磁性纳米粒子的磁功能化碳纳米管 (MFCNT)。该算法基于应用 Galerkin 投影法求解麦克斯韦方程的三维衍射问题以及 Landau-Lifshitz 方程。在毫米和太赫兹频率范围内,根据特性方程,通过所开发的计算 MFAB 传导矩阵的计算算法,对在三维 MFCNT 阵列中传播的纵波和横波的复文数进行了电动计算,并将其作为偏置场大小的函数。
