Purpose
– In this contribution, the aim is to present a nanoparticle device, operating in the visible regime based on the localized surface plasmon resonance (LSPR) phenomenon.
Design/methodology/approach
– The nanoparticle electromagnetic properties are evaluated by a new analytical model and compared to the results obtained by numerical analysis.
Findings
– A near-field enhancement is obtained by arranging the nanoparticles in a linear array. Analytical formulas, describing such enhancement, are presented.
Originality/value
– The results demonstrate the possibility to use the proposed device for medical diagnostics and optoelectronics applications.
