Computes the total flux and radiation pattern of a dipole in a disc. Args: zpos: height of dipole above ground plane as fraction of disc th

Computes the flux from a dipole in a slab. Args: zpos: position of dipole as a fraction of layer thickness. rpos_um: position of sour

The discretization errors tend to result in a *shift* of the spectral features more than a change in their amplitude. Because these features ar
