Abstract :
From microscopic quantum electrodynamic model of interaction between electromagnetic field and a linear dielectric medium, the Hamiltonian for electromagnetic field in a nanostructured medium is constructed. The Hamiltonian determines the quantum properties of field with medium taken as structured continuum. We use macroscopic material parameters for medium and creation and annihilation operators to represent the fields. The electric field distribution in the structured medium is determined by taking expectation value of electric field operator with field in coherent state.
