propagation_matrix
==================

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.propagation_matrix
   :type: ~pyarts3.arts.PropmatVector
   
   This contains the fully polarized propagation matrix for the current path point.
   
   The propagation matrix can be used to computed the transmission matrix as:
   
   .. math:: \mathbf{T} = \exp\left(-\mathbf{K} r\right),
   
   where :math:`\mathbf{K}` is the propagation matrix, and :math:`r` is some distance
   over which it is considered constant.
   
   The unit is [1 / m].
   
   Dimension: :attr:`~pyarts3.workspace.Workspace.frequency_grid`.
