Enhancement of the Electromagnetic Waves Intensity by Scattering on Multiple Infinite Cylinders

摘要

We report the effect of multiple cylinders scattering of electromagnetic plane-wave on formation of high field intensity areas. Our model consists of three cylinders. One of them was basic and the possibility of the existence of high intensity field which can form in its vicinity has been studied. Two values of the radius for basic cylinder were considered: a resonant radius when the so-called whispering gallery modes formed, and non-resonant. It was found that a focal length of photonic nano jets generated at the shadow-side surface of basic cylinder increased (up to two times) compared to the case of a single cylinder. For whispering gallery modes the field intensity also increased up to two times.
