Abstract
The indefinite admittance matrix of the uniform R-C-NR structure (1) is written in a modified manner. The new expressions for the admittance parameters are expanded utilizing the technique postulated earlier by Dutta Roy and Kumar (2). A rational two-port lattice equivalent of the uniform R-C-NR structure is constructed. This proposed model is much more accurate over a much wider frequency range and is very much improved because it stimulates the characteristics more precisely and extensively.
