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 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 ...

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 ...

Silicon solar cells still require cost reduction and improved efficiency to become more competitive. New architectures can provide a significant increase in efficiency, but today most of the approaches need additional processing steps. In this context, laser processing offers a unique way to replace technological steps like photolithography that is not compatible with the requirements of the ...

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 ...

Introduction: A metal film whose thickness is smaller than the skin depth, is of high transmission in the visible and half-transparent in the near infrared. However, when the film is divided into discrete nano-strips (i.e. array), an enhanced anomalous reflection and suppressed transmission take place. It was reported that this phenomenon is attributed to the Localize Surface Plasmon Resonance ...
