Technological progress and the perpetual learning curve [Spectral Lines]

ABSTRACT:

Taking the impedance mismatch of transmission lines as a small amount, a unique impedance perturbation theory based mostly on the lumped transmission line model is established for each the one-ended and coupled transmission lines. The propagation constant, S-parameters, and T-parameters will be directly made from an impedance perturbation factor. As an application example, a detailed perturbation analysis is distributed for differential striplines, that provides insights within the S-parameter features and therefore the splitting in the modal propagation constants. The corresponding numerical simulation indicates that the perturbation model captures and explains the most vital features of the precise S-parameters. As another application example, the perturbation model is utilized in the through-reflection-line deembedding formulas to guage the measurement accuracy and sensitivity. The trends obtained by this analysis is later confirmed by experimental results.
