      package to model antenna near- and far-field radiation patterns for
      Linux and UNIX operating systems. The original FORTRAN version of NEC2
      was ported to C by Neoklis Kyriazis, 5B4AZ and released as nec2c. Later
      he wrote xnec2c, a graphical interface for ease of use with many more
      features.

TeleSculptor is a cross-platform desktop application for photogrammetry. It was designed with a focus on aerial video, such as video collected from UAVs, and handles geospatial coordinates and can make use of metadata, if available, from GPS and IMU sensors. However, the software can also work with non-geospatial data and with collections of images instead of metadata. TeleSculptor uses Structure-from-Motion techniques to estimate camera parameters as well as a sparse set of 3D landmarks. It uses Multiview Stereo techniques to estimate dense depth maps on key frame and then fuses those depth maps into a consistent surface mesh which can be colored from the source imagery.

Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for the analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM) and it supports a lot of SPM data formats. However, it can be used for general height field and (greyscale) image processing, for instance for the analysis of profilometry data or thickness maps from imaging spectrophotometry.Gwyddion provides a large number of data processing functions, including all the standard statistical characterization, levelling and data correction, filtering or grain marking functions. And since the developers are active SPM users, the program also contains a number of specific, uncommon, odd and experimental data processing methods they found useful – and you may find them useful too.

      Lightwave explorer is an open source nonlinear optics simulator, intended to be fast, visual, and flexible for students and researchers to play with ultrashort laser pulses and nonlinear optics without having to buy a laser first. Supports both CUDA and CPU calculations. Its purpose and goals are:
    
      
        Easily-extensible database of materials
        Multiple physical models, including the unidirectional nonlinear wave equation and finite-difference time-domain approaches.
        Efficient code so that complicated systems can be simulated in 3D: Real laser pulses can be messy, and if they weren't so before a nonlinear crystal, there's a good chance they are after. Multidimensional simulations open up the weird world of spatiotemporal couplings. You have options for very fast simulations when there's a symmetry to use (e.g. cylindrical), alongside fully 3D propagation
        A graphical interface that lets you see what you're doing
        A flexible sequence mode to string together elements: not just nonlinear crystals, also spherical or parabolic mirrors, apertures, filters, free space propagation and more
        Fitting/optimization routines
        A Python module for easy postprocessing
