The problem of reflection and transmission of electromagnetic wave through multi-layer bi-isotropic media is analyzed by nonsymmetric transmission-line model. The formula of reflection and transmission coefficients is deduced. To compare with the results in previous literatures, some numeral examples are presented. The comparison shows that our result accords with that of literatures. It is convenient for calculating the reflection and transmission of electromagnetic wave through multi-layer bi-isotropic media. At the same time, both the changes in nonreciprocal and chiral parameters have larger effects on reflection and transmission coefficients.
