The NANOBEM25 toolbox provides a MATLAB-based implementation of the boundary element method (BEM) tailored for simulating optical properties of nanostructures.
In addition to core BEM functionality, this toolbox includes several add-ons developed for:
-
Optical tweezers simulation — based on extensions described in
ACS Photonics 2015, 2, 1023–1030 -
Optofluidic force induction (of2i) modeling — covering the underlying physics as detailed in
Phys. Rev. Applied 19, 034041 (2023) -
Interference microscopy - extending the capabilities of the toolbox to microscopy and imaging-related tasks often encountered in nanosensing as reported in ACS Photonics 2024, 11, 2745-2756
These enhancements make the toolbox suitable not only for nanoplasmonics research, but also for optical trapping and particle characterization in photonic experiments.
To use the NANOBEM25 toolbox, you must add at the beginning of each session the main directory and all subdirectories to the Matlab path, e.g. by calling
addpath(genpath(NANOBEMDIR) );
Here, NANOBEMDIR is the full directory name of the toolbox.
To set up the NANOBEM25 help pages, you must install them once.
To this end, you must
(1) change in Matlab to the main directory of the NANOBEM25 toolbox, and
(2) run the file makehelp.m.
A detailed help of the Toolbox and a number of demo files are then available in the Matlab help pages which can be found on the start page of the help browser under Supplemental Software.
If you use this toolbox in your work, please cite all of the above-mentioned papers.
