The authors propose a method for the off-axis directional beaming of optical field diffracted
by a single subwavelength metal slit with dielectric surface gratings. In the proposed …

Although recent advances in biosensing are promising, there still is a need for label-free,
sensitive, and cost-effective detection of single nanoparticles and single biomolecules …

Although plenty of carbon dots have been synthesized by many kinds of synthesis methods,
their potential in metal sensing applications is still limited. Herein, the application of carbon …

In recent years, multilayer photonic bandgap structures comprising stacks of alternating
layers of positive and negative index have been proposed for a variety of applications, such …

The FDTD method was used to simulate focused Gaussian beam propagation through
multiple inhomogeneous biological cells. To our knowledge this is the first three dimensional …

A novel vanadium–cellulose composite thin film-based on angular interrogation surface
plasmon resonance (SPR) sensor for ppb-level detection of Ni (II) ion was developed …

We analyze and propose a thin-film patterning method based on Kretschmann's attenuated
total reflection (ATR) configuration where the surface plasmon mode and plasmon coupled …

In this paper, some biological sensors based on surface plasmon resonance are proposed
at visible and near-infrared wavelengths and their performance is improved. The structure of …

Superprism effect is exhibited in one-dimensional thin film stacks due to their abnormal
dispersion and anisotropy properties near the bandgap. Thin film Fabry-Perot filter (FPF) …

A new scheme of variable thickness ladder-like stepped metal film for simultaneous
excitation of surface plasmon resonance (SPR) with different wavelength based on modified …
