WINSPALL software for surface plasmon resonance experiments

One needs to fit the reflectivity curves obtained in surface plasmon resonance experiments with theoretical models. A free software (for non commercial use) called Winspall exactly does that. According to the developers, WINSPALL is a PC based software which computes the reflectivity of optical multilayer systems. It is based on the Fresnel equations and the Read More …

Dynamic Exciton-Plasmon Coupling

Our paper titled “Dynamically Tuning Plasmon-Exciton Coupling in Arrays of Nanodisk-J-aggregate Complexes” has been accepted as front cover image of Advanced Materials . In this work, we demonstrated the dynamic tuning of plasmon-exciton resonant coupling in arrays of nanodisk–J-aggregate complexes. The angle-resolved spectra of an array of bare Au nanodisks exhibited continuous shifting of localized Read More …

Radiation from an oscillating dipole

The electric field from an oscillating dipole is given by:, where is the position vector, is the frequency of dipole oscillation, is the dipole moment. The two terms in the electric field consists of 1) near field (area near to the dipole) and 2) far field (area far from the dipole) contributions. Far field falls Read More …

Resources on Electromagnetics/Plasmonics/Nanophotonics

These are some resources on Electromagnetics/plasmonics/nanophotonics I will maintain a list of free resources on electromagnetics, plasmonics, nanophotonics, optics and other related topics here. If any of you (readers) know any other free resources related to this topic, please let me know and I can add into these lists. Free books: Electromagnetic waves and Antennas Read More …
