`lead_info[i].wave_functions` contains the wavefunctions of the propagating modes in lead `i`. This is a 2D array, where the first axis corresponds to the orbitals in a unit cell of the lead, and the second axis is the mode number. These wave functions are essentially the unit-cell-periodic part of the Bloch states in the lead. It makes sense that the length of the second axis can be different depending on the energy, as at different energies there may be different numbers of propagating modes open in the lead. Hope that helps, Joe
