Finite size effects on topological interface states in one-dimensional scattering systems
P. A. Kalozoumis, G. Theocharis, V. Achilleos +3
One-dimensional topological edge modes are usually studied considering the interface between two different semi infinite periodic crystals (PCs) with inverted band structure around…

Scattering by finite periodic -symmetric structures
V. Achilleos, Y. Aurégan, V. Pagneux
In this work, we study the transmission properties of one dimensional finite periodic systems with -symmetry. A simple closed form expression is obtained for the tota…
