    nanoBIO node Plasmonics and Its Applications Workshop

    The study of plasmonics has been around for several decades now. The study of the interaction between the electromagnetic field and the free electrons in metal have been found as advantageous...

    nanoBIO node Webinar Series (Plasmonics Devices Modeling and Simulation)

    This is the nanoBIO node webinar series on online modeling and simulation of:

    nanosystems plasmonics using

  3. Shape Generator for the Discrete Dipole Approximation

    28 May 2015 | Downloads | Contributor(s): Manoj Seeram, Gregory T. Forcherio, Phillip Blake, D. Keith Roper

    Youtube video link showing program in use: Description This Matlab Graphical User Interface walks users through creating custom 3D shapes. It then...

  4. Error while compiling DDACONVERT code.

    Closed | Responses: 2

    I want to locally compile the DDACONVERT tool on my Linux Ubuntu system. After downloading the code I tried to rum the make command in SRC directory via terminal and the following error was...

  5. Clarify Mueller Matrix returned by DDSCAT

    Open | Responses: 1

    I'm making Mueller Matrix measurements of silver nanocubes as part of my dissertation research at Air Force Institute of Technology. I'm trying to compare measurement to results...

  6. nanoDDSCAT+

    13 Aug 2014 | Tools | Contributor(s): AbderRahman N Sobh, Sarah White, Jeremy Smith, Nahil Sobh, Prashant K Jain

    Combines the Discrete Dipole Scattering (DDSCAT) tool with the DDAConvert tool for a single workflow for custom shapes.

  7. How to modify the code to run with only gfortran and without openmpi installed in the system?

    Closed | Responses: 1


    I am a neophyte in linux and don't have iFort and openmpi installed in my Scientific Linux. If you could help me to run it without those it will be very helpful.

  8. How can I change the Intensity scale?

    Closed | Responses: 3

    I would like to be able to see small changes in the intensity display. The electric field displays in just one color right now because there is very little variation in the intensity. I would...

  9. Can the simulation save data for future use?

    Closed | Responses: 1

    After running various simulations I wondered if the program can save the data obtained which then can be retrieved at a different time. For example if I were to publish a paper using your...

  10. How soon will the software be able to set the rotation of the object relative to the incident light?

    Open | Responses: 1

    I know that the option is hidden for now, “working on a gui based method to set the rotation of the object relative to the incident light.” I would like to know if it is possible to...

  11. Is there a way to change the polarization direction for the x axis to the y or z?

    Open | Responses: 2

    In the code I see ****define incident polarizations **** (0,0) (1,0) (0,0) = Polarization state e01 (k along x axis) Lets say I would want to observe the polarization of the object from a...

  12. can the Storage limit be increased?

    Closed | Responses: 3

    I am currently running some simulations and I would like to know if the storage for the ddscat tool be increased to 5 GB. This would allow more detailed simulations to be obtained.

  13. why does the 3D field electric field feature complie all previous simulations?

    Open | Responses: 2

    After doing a few simulations I noticed that in the 3D electric field feature seemed to keep previous simulations and I can not have it focus on one. I did unpress the ALL button but previous...
