ELECTRIC-FIELD-ENHANCEMENT STRUCTURES INCLUDING DIELECTRIC PARTICLES, APPARATUSES INCLUDING SAME, AND METHODS OF USE

摘要

In one aspect of the present invention, an electric-field-enhancement structure (100) is disclosed. The electric-field-enhancement structure (100) includes a substrate (104) and an ordered arrangement of dielectric particles having at least two adjacent dielectric particles (102, 103) spaced from each othera controll3d distance (S). The controlled distance (S) is selected so that when a resonance mode is excited in each of the at least two adjacent dielectric particles (102, 103) reponsive to excitation electromagnetic radiation, eqch of the 4esonance modes interacts with each other to result in an enhanced electric field between the at least adjacent die;ectric particles (102, 103). Other aspects of the present invention are electric-field-enhancement apparatuses (1000) that utilize the described electric-field-enhancement structures, and methdos of enhancing an electric field between adjacent dielectric particles.
