چکیده

Abstract Electromagnetic anapole mode is a nonradiative state of light originating from the deconstructive interference radiation oscillating electric and toroidal dipole moments. The high quality anapole-related resonances can be used in enhancing nonlinear electromagnetic properties materials sensor applications. In this work, we experimentally demonstrate plasmonic metamaterial environmental refractive index optical part spectrum. Our results show that exhibits sensitivity to ambient at level 330 nm/RIU noise floor 8.7 × 10 -5 RIU. This work will pave way for applications metamaterials biosensing spectroscopy.

Universal scaling of plasmonic refractive index sensors.

We establish experimental and numerical evidence that the refractive index sensitivities of various subwavelength plasmonic sensors obey a simple universal scaling relation that the sensitivities linearly increase with λm/neff (where λm is the resonant wavelengths and neff is the effective refractive index of the environment) and exhibit a slope equal to 1 instead of 2 predicted theoretically. ...

Plasmonic Refractive Index Sensor with High Figure

A plasmonic refractive index (RI) sensor based on metal-insulator-metal (MIM) 11 waveguide coupled with concentric double rings resonator (CDRR) is proposed and investigated 12 numerically. Utilizing the novel supermodes of the CDRR, the FWHM of the resonant wavelength 13 can be modulated, and a sensitivity of 1060 nm/RIU with high figure of merit (FOM) 203.8 is realized 14 in the near-infrared...

Multiple Fano-Like MIM Plasmonic Structure Based on Triangular Resonator for Refractive Index Sensing

In this paper, we present a Fano metal-insulator-metal (MIM) structure based on an isosceles triangular cavity resonator for refractive index sensing applications. Due to the specific feeding scheme and asymmetry introduced in the triangular cavity, the resonator exhibits four sharp Fano-like resonances. The behavior of the structure is analyzed in detail and its sensing capabilities demonstrat...

Plasmonic circular resonators for refractive index sensors and filters

A plasmonic refractive index sensor based on a circular resonator is proposed. With all three dimensions below 1 μm, the sensor has a compact and simple structure granting it ease-of-fabrication and ease-of-use. It is capable of sensing trace amounts of liquid or gas samples. The sensing properties are investigated using finite elements method. The results demonstrate that the plasmonic sensor ...
