Surface plasmon resonances on cones and wedges
2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2014We consider the hypersingular plasmonic surface modes that are supported by a 3D negative-permittivity circular conical tip and study how their occurrence depends on the opening angle and permittivity of the cone. A comparison to a 2D wedge is made.

Surface plasmon resonance phase imaging
Applied Physics Letters, 2000We present a promising optical system and technique for detection, imaging, and visualization of minimal changes, of the order of 10−6 in refractive index, in the near field. The system is based on phase imaging of excited surface plasmons in a conducting layer in contact with a sample.

Introduction to Surface Plasmon Resonance
2021Several first-in-class drug targets (kinases, dedrogenases, reductases, transferase, etc.) suffer from validation in primary assays due to lack of proper reference molecules. In the absence of reference molecules against any drug targets, the Surface Plasmon Resonance (SPR) based approach will be beneficial for the development of small molecule ...

An Inverted Surface Plasmon Resonance
Journal of Modern Optics, 1993Abstract An inverted surface plasmon resonance is observed by measuring the internal reflectivity of a bilayer chromium-gold thin film deposited on a high index glass prism. With incident transverse magnetic radiation and suitable choice of chromium and gold thicknesses a strong resonance maximum is recorded which is nearly as narrow as the more ...

On-Chip Surface Plasmon Resonance Sensor
Journal of Nanoscience and Nanotechnology, 2008A novel on-chip micro SPR (surface plasmon resonance) sensor based on an optoelectronic platform has been developed. This research aims for a fully integrated SPR sensor system to achieve a miniaturized, high throughput sensor system. A novel method for design and fabrication of the solid state SPR sensor device has been investigated.

Surface Plasmon Resonance-Based Methods
2012Surface plasmon resonance represents a new tool for the simple, fast and cheap nucleic acid detection. Large efforts have been paid during the last decade with the aim to develop even more sensitive and specific SPR-based methods to be used for the direct detection of genomic DNA.

Physics of Surface Plasmon Resonance
2008In the last two decades, surface plasmon resonance (SPR) has evolved from a fairly esoteric physical phenomenon to an optical tool that is widely used in physical, chemical and biological investigations where the characterization of an interface is of interest.

Localized Surface Plasmon Resonances
2017Surface plasmon polaritons are propagating energy waves at a plane metallic–dielectric interface. Metallic nanoparticles supply an effective restoring force to drive electrons in an oscillating electromagnetic field. A specific resonance condition leads to a field amplification localized in the near zone inside and outside the particle.
