SPP Diffractive Lens as One of the Basic Devices for Plasmonic Information Processing

Abstract

The concept of the in-plane SPP curvilinear FZP-like lens, which will have a significant impact in science and technology, is offered. The adaptation of free-space 3D binary phase-reversal conical Fresnel zone plate for operation on SPP waves demonstrates that analogues of Fourier diffractive components can be developed for in-plane SPP 3D optics.
