Electromagnetic Field Simulation of Nanometric Optical Tweezers.

This paper shows how the frequency domain solver of CST MICROWAVE STUDIO® (CST MWS) can be used to calculate the near field distribution of metallic and dielectric objects at optical frequencies. This web paper is based on the publication “Theory of Nanometric Optical Tweezers” by Lukas Novotny, Randy X. Bian, and X. Sunney Xie, Physical Review Letters, Volume 79, No. 4, 28 July 1997.

Plane Wave Interactions with a Dielectric Half-Space at 60 THz

In this article, CST MICROWAVE STUDIO® is used to illuminate an infinite dielectric half-space with a uniform plane wave and the reflection and transmission quantities are obtained. This problem has an analytical solution which serves to validate the simulation. The same procedure is then applied to a more generalized geometry which lacks a known analytical solution.

Light Trapping in Thin-Film Silicon Solar Cells with periodic Nano-Structures

This article summarises the simulation study conducted with CST MICROWAVE STUDIO® (CST MWS) of thin-film silicon solar cells with nano-structured interfaces. The good agreement between the experimental data and solar cell simulations shows the reliability and versatility of the performed FIT simulations to investigate nano-optics of thin-film solar cell devices in 3 dimensions. This article is presented with the courtesy and permission of Hasse, C. and Stiebig, H. , Forschungszentrum Juelich who gave a presentation of their work at the CST European User group Meeting at Boppard, Germany, 9-10th March 2006.
