Numerical evaluation of the Greens's functions for cylindrical enclosures by a new spatial images method

In this paper, a spatial images technique is used to efficiently calculate the mixed potential Green's functions associated to magnetic sources when they are placed inside a circular cylindrical cavity. The technique places magnetic dipole images and charges outside the cylindrical region. Thei...
