pyScatSpheres 1.0.3.dev3

Scattering of array of spheres, scalar theory

pyScatSpheres

Package for solving the scalar wave equation with a linear array of scattering spheres. Possibility to solve for constant potential well and hard spheres i.e. infinite potential.

Installation

pip install pyScatSpheres

Using the GUI

A gui is available to interactively display pre calculated solutions.

from pyScatSpheres import gui_base as gui
sa = gui.GUI_handler()

Using the API

New sets of solution can be calculated and solved to a pickle using the API.
