The problem of measurement of the block-diagonal scattering matrix is addressed. It has been shown that non-zero elements of the scattering matrix with block-diagonal structure can be measured using only two polarizations of input radiation. Optimal pairs of these polarizations are derived. Utilization of the optimal input polarization results in half the measurement time and a decrease in measurement errors of approximately 30%.
