A transfer matrix method is presented for the determination of complex eigensolutions associated with the damped torsional vibrations of single shaft machine trains. The system is described and the natures of the eigenvalues are discussed. The general solution method is developed, and the method is applied to two example problems. One of the examples is quite simple, while the other is entirely realistic.

In this paper, we present current-voltage model characterization calculation of Ba0.5Sr0.5TiO3ferroelectric-based solar cell to determine its effective mass. Numerical calculation was done using Transfer Matrix Method (TMM). Fitting between the calculations results with experiment data can be done by approximating the Ba0.5Sr0.5TiO3effective mass value. Ba0.5Sr0.5TiO3effective mass can be obtained when both data fit.

Double barrier structures with a gradient have been studied by numerical calculations of transmission coefficient following a transfer matrix method. As the slope of the barriers becomes steep, the resonant energy is lowered. On the other hand, the full width at half maximum does not depend on the gradient.
