edges_cal.reflection_coefficient

Functions for working with reflection coefficients.

Most of the functions in this module follow the formalism/notation of

Monsalve et al., 2016, “One-Port Direct/Reverse Method for Characterizing VNA Calibration Standards”, IEEE Transactions on Microwave Theory and Techniques, vol. 64, issue 8, pp. 2631-2639, https://arxiv.org/pdf/1606.02446.pdf

They represent basic relations between physical parameters of circuits, as measured with internal standards.
