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 ...

Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their size, shape and dielectric environment, and they have long-term stability. In this work, an ultrathin polymer ...

Surface plasmon resonance (SPR) sensors proved themselves as a promising device for many kinds of applications such as optical biosensing, binding constant determinationor nanofilm thickness measurements. Here we simulate using COMSOL Multiphysics® the light-polaritons coupling for the two most commonly used SPR setups: Attenuated total reflection (Kretschmann configuration) and diffraction ...

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 ...

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 ...

COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries on confinement loss spectra were studied, which agreed well with the high-loss and low-loss bands predicted ...

A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this electric field enhancement is a key challenge for a wide range of applications such as surface modification, data ...
