Internal electric-field intensity distribution of a monolayer of periodically arrayed dielectric spheres

Theoretical analysis is given for the internal electric-field distribution of two-dimensional periodic dielectric spheres by extending the vector Korringa-Kohn-Rostoker method. It is shown that the internal electric-field intensity distribution of the monolayer with high dielectric constant is in good agreement with that of an isolated sphere at the Mie resonance. In contrast, the field distribution of the monolayer with low dielectric constant is complicated and strongly influenced by the interaction between spheres. Our results show that the internal electric field of the monolayer presents important information about the origin of each eigenstate.
