The paper presents the results of experimental research into the effect of air corona plasma on a surface of plasmon coatings and its optical properties. The surface plasmon resonance (SPR) method was used as an experimental tool. To the best of our knowledge, no research has been made in this field. We have discovered that negative and positive corona(More)
Surface plasmon resonance (SPR)-based sensors are widely used today for express analysis of liquid biological mediums in microbiology, medicine and genetic engineering. They are also used for detecting different contaminants in gaseous mediums. In this case, the main problem of such sensors development is choosing of selective sorbents applied to the sensor(More)
Significant changes of the permittivity of a silver film have been detected using the surface plasmon resonance (SPR) method when a constant electric field is applied to the 177-nm dielectric corundum film placed between two silver films 49 nm and 36 nm thick. The effect manifests itself as a significant change of the reflectivity of the structure when the(More)
We present an optical computing system to solve NP-hard problems. As nano-optical computing is a promising venue for the next generation of computers performing parallel computations, we investigate the application of submicron, or even subwavelength, computing device designs. The system utilizes a setup of exponential sized masks with exponential space(More)
