Purpose
– The purpose of this paper is to contribute an analytical and numerical study of a new type of nanoshell particles operating in the visible regime.
Design/methodology/approach
– The structure consists of a core/shell particle, arranged in a planar array configuration, with a polymethyl methacrylate (PMMA)-graphene core and gold thin shell.
Findings
– By exploiting the proposed analytical model the design of a metamaterial-based sensor, operating in the optical frequency range, for the detection of tissue diseases is shown.
Originality/value
– Full-wave simulations confirm the capability of the proposed sensor to identify different compounds by refractive index measurement.
