The properties of two supernova remnants, SNR 3C 391 and SN 1006, are theoreti-cally re-analyzed. Comparing data from previous studies ([6] and [9]) with theoretical models we determine astronomical parameters such as the spectral index, optical depth, magnetic ﬁeld and ﬂux density at key frequencies. A weighted least-squares ﬁt of the data will allow us to study the turnover for low frequencies in the continuum spectrum of SNR 3C 391 caused by free-free thermal absorption of a gas directly linked to the remnant. Multiple origins of the ionized absorbing gas are discussed, such as a warm ionized medium, HII regions and the encounter of the supernova remnants shock wave with a molecular cloud. On the other hand, a linear least-squares ﬁt is the method chosen for studying the continuum spectrum for SN 1006. Comparing our results with the ones obtained by Berezhko et al. 2012 using the kinetic theory of cosmic rays we will be able to prove the consistency of this theory
