Overview

Analytical modeling study reveals electric and magnetic field enhancement in subwavelength silicon dimers, indicating strong potential for low-loss dielectric spectroscopy and sensing.

Key Points

To investigate the electromagnetic interactions and field-enhancement properties of low-loss, high-refractive-index dielectric nanoparticle dimers for electric and magnetic field-enhanced spectroscopy.
Applied an analytical dipole–dipole interaction model to analyze scattering spectral features and near-field enhancement within subwavelength dielectric dimers.
Calculated quantum efficiencies along with radiation rate enhancement and quenching for electric and magnetic dipole emitters located in the dimer gap, benchmarking results against metallic dimers.
Identified that dielectric dimers exhibit coupled magnetodielectric behavior, producing simultaneous electric and magnetic near-field enhancements within the particle gap.
Demonstrated that high-index dielectric dimers yield favorable quantum efficiencies and minimize nonradiative quenching compared to plasmonic metallic dimers.
