A new improved transfer matrix method (TMM) is presented. It is shown that the method not only overcomes the numerical instability found in the original TMM, but also greatly improves the scalability of computation. The new improved TMM has no extra cost of computing time as the length of the homogeneous scattering region becomes large. The comparison between the scattering matrix method (SMM) and our new TMM is given. It clearly shows that our new method is much faster than the SMM.
