The Mie solution to the scattering of electromagnetic waves by spherical particles has been examined using COMSOL Multiphysics®. The results assume elastic scattering only and do not include Brillouin or Raman scattering. The nature of the interaction has been considered for materials with three different properties: metallic, magnetic and dielectric. The solutions provide details of the ...

This paper presents a study on the propagation modes of electromagnetic waves through a step index fiber optics. To analyze the propagation of electromagnetic field, a simulation in Comsol 4.0 has been implemented using two different optical fibers. Obtaining the propagation modes, called linearly polarized modes (LPnm) to get their characterization according to the radial and azimuthal ...

The resonance conditions for surface plasmons are influenced by the type and amount of material on a surface. Full insight into surface plasmon resonance requires quantum mechanics considerations. However, it can be also described in terms of classical electromagnetic theory by considering electromagnetic wave reflection, transmission, and absorption for the multi-layer medium. The two commonly ...

Solar energy is the cleanest form of renewable energy. The most popular form of utilization of solar energy is through the use of photovoltaic cells. Currently the efficiency of available solar cells lies below 20%. To increase the efficiency, multi-junction can be used in solar cells. While developing such devices we need platform to study various characteristics and parameters to optimize ...

Surface Plasmons (SP) or Surface Plasmon Polaritons (SPP) are electromagnetic excitations that propagate at the interface between a dielectric and a conductor, and are evanescently confined in the perpendicular direction to the propagation. They arise via coupling of the electromagnetic field to oscillations of the conductor’s electron plasma and are characterized in terms of dispersion and ...

This paper introduces the concept, research methods and application of photonic crystals. Starting from Maxwell's equations, the functional form of the TE mode and TM mode of the 2D crystal is derived. In 2D crystal, according to the functional forms, we conduct some stimulation about two-demensional photonic crystal with line-defect and dot-defect, forming some results as following: 1. ...

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection process or material attributes that allow them to be selected as candidates in solar dryer designs. 1–7 ...

Introduction: Flat lenses require precise control of a phase gradient across an interface, which is enabled through the application of engineered surfaces, such as Metasurfaces . Periodic arrays of plasmonic antennas have been utilized to generate this desired phase gradient, which dictates the angle of “anomalous” refraction of the cross-polarized field scattered from a normal-incidence ...
