麦克斯韦电路理论的研究与发展

基于基尔霍夫定律导出的传输线方程在低频领域具有良好的适用性,但是随着频率的提高它渐渐失去了精确性。最近提出的麦克斯韦电路理论从"场"的观点出发,推导出传输线方程的完备形式。研究表明,麦克斯韦电路理论不仅适用于"路"的问题,还适用于"场"的问题。目前的工作表明,对于任何线结构的电路和电磁场问题,包括线天线问题和传输线问题,该理论具有良好的适应性。计算结果与矩量法计算结果一致。本文介绍这一理论的建立、发展和研究近况。     

Analyzing multi-circular loop scatterers by Maxwellian circuits

Calculating the current distribution in circular loop scatterers commonly involves complicated computation. In this paper, based on the theory of Maxwellian circuits (MC), we propose a fast algorithm by solving a wave equation with constant parameters corresponding to the circular loop. Our method prodeces similar results compared to the methods using method of moments (MoM) with lower computational complexity. It is effective when there are parallel multiple circular loop scatterers. Experimental results show accuracy of the method.
