Transfer Matrix Approach For Plasmon Scattering In Closely Packed 1D Graphene Structures

ORAL

Abstract

We present a comprehensive study of graphene plasmon eigenmodes in 1D periodic structures formed by plasmonic junctions of different types [1]. Transmission and reflection coefficients composing a junction's scattering matrix are obtained directly from numerical solutions of equations describing the plasmons in the considered structures. The single junctions' obtained results are in perfect agreement with analytical formulas for the cases when they are available. Using our method as a reference, we analyze the limitations of the semi-phenomenological transfer matrix approach applied to the calculation of reflection from the double-junction structures. Our results can be useful in designing and calculating graphene plasmon resonators, waveguides, and switches.
