A phenomenological description of optical near fields and optical properties of N two-level systems interacting with optical near fields

Abstract

In this chapter, we present a simple phenomenological model of an optical near fields interacting with two-level systems and discuss the dynamics of dipole excitation and radiation properties of the system. As a result, we find that the locally near-field coupling enables controlling the dipole distributions by manipulating the initial excitations and causes strong oscillating radiation pulses. Transport phenomena of the near-fields photons through material systems shows switching between flow and block depending on the coupling strength between material systems and near-field photons.
