Subwavelength negative-index waveguiding enabled by coupled spoof magnetic localized surface plasmons

Listed in DataCite

Magnetic localized surface plamsons modes are supported on metallic spiral structures.

Description

Coupling mechanisms for this metamaterial resonators are studied, which are the joint action of magnetic and electric coupling. Based on the strong coupling, localized surface magnetic modes propagating with backward direction are proposed along a chain of subwavelength resonators.

The numerical simulations and experiments are in good agreements. The proposed novel route for achieving negative-index waveguiding has potential applications in integrated devices and circuits. 1. Introduction
