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.
