摘要
Analysis of the scattering parameters（S-parameters） of planar N-way metamaterial power dividers/combiners mostly uses commercial microwave circuit simulators due to the large circuit size involved. This paper presents an efficient circuit modeling approach, which is based on the multi-input and multi-output transmission matrix（T-matrix） method, to analyze the S-parameter of a planar nine-way metamaterial power-divider/combiner structure. S-parameter computation results are shown in good agreement with the simulation results by using the Agilent advanced design system（ADS） and measurement results. The computation time of an N-way metamaterial power divider/combiner with N=5, 9, 13, and 17 using T-matrix method is also compared with those of ADS and AWR Microwave Office（MWO） to demonstrate its computational efficiency.
