Coupled dipole approximation (CDA) method is a numerical method to calculate the optical properties (scattering and absorption) of interacting dipoles. This method is used in discrete dipole approximation method (like …

Here is how I was implementing plasmonic materials in meep1.1 scheme code. Unlike Meep 1. 1, Meep >= 1. 2 changed the way materials are defined. Here I will describe …

Pre-compiled Meep binaries for meep1.1 exist for Ubuntu distribution. This makes it very easy to install meep on ubuntu using “apt-get install” command or from the ubuntu software center. However …

This article is about simulating localized plasmon resonances in metal nanospheres using MEEP package. Generally, I am interested in solving three problems in LSPR systems:

Calculate the extinction, scattering, absorption spectra …

A thin metal film in dielectric (also known as dielectric-metal-dielectric configuration) can support surface plasmons that are different in nature to the ones observed in thick metal-dielectric interfaces. Unlike, a …

In MEEP (1.1.1), dielectric structures are often created by constructive geometry (adding and subtracting primitive shapes). The primitive shapes that are allowed are blocks, cylinders, ellipsoids and cones. To create …

The aim of this post is to share my experience in incorporating dielectric function of metals such as gold and silver into MEEP (a free finite difference time domain package) …

It is important to know the magnitude and distribution of electric field near the metallic nanoparticles at plasmon resonance. One can look at the electric field and say whether the …

Discrete Dipole Approximation (DDA) is an important tool in plasmonics research. Using DDA, one can calculate scattering properties of nanoparticles at various wavelengths, polarizations and surrounding medium. The specialty of …

Since 2009, I have been a regular user of Nanohub.org. www.Nanohub.org is a website that provides a platform for online simulation, research and teaching resources. Of interest is the ability …
