Note: In nanoelectronics, surface plasmon intensification is the coordinated and cumulative oscillations of metal electrons that are excited by radiation.In electronic science, the topic of nano revolves around (nano memories, nano chips and fast nano chips and nano electronic components) with less weight and more efficiency.  Nanotechnology, knowledge, engineering and technology on a nano scale, or in other words, studying the application of very small objects and their use in all fields of science such as chemistry, biology, electronics; Material science and engineering. The history of nanotechnology describes the development of concepts and experimental work done in the field of nanotechnology. Although nanotechnology is one of the recent advances in scientific research, the development of its fundamental concepts has taken place over a long period of time. The condition of oscillation is that the frequency of the photons of the radiated beam becomes the same as the natural frequency of the surface electrons (which is to overcome the central nuclear force). The resonance of surface plasmons in structures with nanometer dimensions is called Localized Surface Plasmon Resonance. Localized surface plasmons are non-emissive excitation of conduction band electrons of metal nanostructures to which an electromagnetic field is coupled. Plasmonic waves are generated by using the scattering problem from a conductive nanoparticle whose dimensions are below the wavelength of the electromagnetic field of the excitation beam. These nanostructures consist of metal and dielectric, whose dimensions are below the excitation wavelength (the wavelength of the radiation that causes the excitation of plasmonic waves). Plasmonic is based on the process of interaction between electromagnetic waves and conduction electrons in metals with nano dimensions.  Analytically, the reason is the rapid drop in the energy of electrons passing through metals, and it was concluded that this energy is spent on the cumulative movement and oscillation of the free electrons of the metal and called it plasmon.
Note:  Since material parameters change significantly with frequency.  In particular, this means that model experiments with, for example, microwaves and larger metallic structures cannot replace experiments with metallic nanostructures at optical frequencies.Surface charge density fluctuations associated with surface nanoplasmons at the interface between a metal and a dielectric can cause strongly enhanced near-optical fields that are spatially confined near the metal surface.  Similarly, if the electron gas is confined in three dimensions, such as a small particle, the overall displacement of the electrons relative to the positively charged lattice leads to a restoring force, which in turn gives rise to the specific particle-plasmon. Resonance depends on the geometry of the particle.  In properly shaped (usually pointed) particles, localized charge accumulation associated with strongly enhanced optical fields can occur. The change of some properties such as conductivity in nanotransistors and electromagnetic properties in nanowires may occur in dimensions of only a few nanometers. Surface plasmon intensification in structures with nanometer dimensions is called local surface plasmon intensification. Patterning magnetic materials into arrays of nanoscale dots can result in a very strong and very controllable change in the polarization of light when a beam is reflected from the array.  This discovery can increase the sensitivity of optical components for telecommunication and biosensing applications. Coupling between light and magnetism in  electrical nanostructures of localized surface plasmons (Localized Surface Plasmon) results from quantum electronic nano interactions.  These interactions lead to magneto-optical effects that change properties, such as the polarization axis or intensity of light.  Interactions between light and matter are enhanced at the nanoscale.  This is a key motivation in the field of plasmonics, which leads to the construction of nanoelectronic devices based on the interaction of light with metal nanostructures. In the structure of electrical nanostructures of localized surface plasmons (Localized Surface Plasmon), a metal nanoparticle in nano size acts very much like an antenna for visible wavelengths.  Such antennas for us in many everyday devices that operate on much longer radio and microwaves   use a phenomenon called surface lattice resonance, in which all nanoparticles, tiny antennas, are coordinated in a The array radiates.The key to this is the assembly of magnetic nanoantennas on a length scale that matches the wavelength of the incoming light. In periodic arrays, nanoparticles strongly interact with each other and cause collective oscillations.  Such behavior is already observed in metal nanoparticles.Since the material parameters change significantly with frequency.  In particular, this means that model experiments with, for example, microwaves and larger metallic structures cannot replace experiments with metallic nanostructures at optical frequencies.
Note: Theory, modeling and simulation  are widely used as a predictive design tool in the reproduction and manufacturing of dynamic molecules of SWCNT nanotubes and SWCNTs.General methods capable of multi-scale/multi-phenomenon molecular simulations will be developed for the design of SWCNT and SWCNTs  nanotubes  and new nanoscale systems and tools. Dynamic nanomolecular simulations will help in various fields such as biosensors, filter design, as well as identifying the dynamics of complex systems of single-layer and multi-layer nanotubes  .The aim of  the simulation methodology in the molecular nanodynamics of nanotubes  is to intervene in the arrangement of atoms or molecules and to use materials and systems with new abilities and  new tasks, which are all the result of the specific multiplication of molecules and particles. Nano is a device with small dimensions and nano structure.Deterministic molecular dynamics simulation: is a method used to  calculate the path of movement of atoms or molecules in multi-atom systems of more than ten atoms to several  billion atoms.Monte Carlo simulation (Stochastic): It is a numerical method that tries to reach the final equilibrium state of the system by sampling the nanomolecular state space with  importance. Based on probabilities, this method brings the configuration of the investigated system close to the minimum energy condition .Initio Ab molecular dynamics:  Initio Ab molecular dynamics or quantum molecular  dynamics performs the movement path of the atomic system by solving the Schrödinger equations and obtaining  information on the subatomic scale.
