Physical admissibility of currentless anomalous sources
Ascertain whether a currentless anomalous source, such as the globally neutral oscillating surface-charge dipole constructed in the compensated-source model, is physically admissible.
References
The tensor comparison also leaves the physical admissibility of a currentless anomalous source unresolved.
