Finite periodic comb

O. I. Hryhorchak, V. S. Pastukhov

A finit periodic comb was solved by the help of both classical approach based on a direct solving of a Sr\"{odinger} equation and a quantum wave impedance method. It was dem…

Analytical representation of an iterative formula for a quantum wave impedance determination in a case of a piecewise constant potential

O. I. Hryhorchak

An analytical solution for a quantum wave impedance in a case of piesewise constant potential was derived. It is in fact an analytical depiction of a well-known iterative method of…
