Metallic nanoparticles supporting a localized surface plasmon resonance have emerged as
promising platforms for nanoscopic labels, sensors, and (photo-) catalysts. To use …

Fourier transform infrared (FTIR) spectroscopy is an important tool for material
characterization. However, due to the diffraction limit, conventional infrared spectroscopy …

Plasmonic photocatalysis uses the light-induced resonant oscillation of free electrons in a
metal nanoparticle to concentrate optical energy for driving chemical reactions. By altering …

A waveguide (WG) excitation-based hyperspectral imaging (HSI) system equipped with a
white-light source and Fourier transform spectrometer is presented. Both the microscopic …

An imaging spectroscopic system that enables spatially-resolved detection of single-particle
scattering with polarization-controlled waveguide excitation scheme is presented. The …

The scattering-type scanning near-field optical microscope (s-SNOM) has become a
powerful imaging and nano-spectroscopy tool, which is widely used in the characterization …

One of the advantages of light controlling is the enhancement of its intensity in localization of
the beam in the near-and far-fields. Our desire is to design a concentric nano elliptical …

The advantage of resonantly THz antennas is the enhancement of electromagnetic fields in
the spectroscopy. Our proposed design includes a spectroscopy setup, which contains THz …
