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 ...

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 ...

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 ...

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 ...

We present a 3D port sweep method in a lossy silicon photonic crystal resonator to demonstrate the capabilities of COMSOL Multiphysics® for frequency domain analysis with input and output ports. This method benefits from the advantages of the S-parameter analysis to characterize the input and output coupling into the resonator. By pumping one end of the cavity with a CW plane wave, we are able ...

Dye sensitized solar cells (DSSCs) have received tremendous attention as alternative photon harvesting devices. While the sintered TiO2 nanoparticle network attached with dye molecules achieves efficient photon absorption, the electrons have to diffuse through the long TiO2 network to reach the contact, resulting in a high electron density and thus increased recombination. Extensive research ...

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. ...
