The solution of the multiple-scattering problem for two parallel infinite dielectric cylinders is considered for plane wave illumination perpendicular to the cylinder axes. Numerical results show the coupling effect with respect to cylinder size, separation, and orientation of the cylinder axes with respect to the incident wave. The coupling effect is illustrated by calculations of the internal and near-field intensity for end-on and broadside incidence. Results for circular cylinders with a size/wavelength ratio corresponding to a particular morphology-dependent resonance (size parameter = 45.329) show that the local effect of the resonance is completely damped when the two cylinders touch.
