Abstract: A hybrid method of the equivalent microwave network technique and aggregated T-matrix algorithm is used to analyze the multiple scattering of parallel circular dielectric cylinders embedded by arbitrary conducting cylinders in this paper. A new formula is derived to relate the T-matrix of conducting cylinders with the impedance matrix of the moment method. The coupled utilization of the numerical method and analytical approach simplifies the analysis of interactions between parallel cylinders.

Key words: equivalent microwave network, aggregated T-matrix algorithm, method of moment, multiple scattering
