In one example embodiment, a magnetic shutter antenna is provided including at least one dipole magnet comprising a first end and a second end and at least one shutter of magnetically soft material comprising at least one opening and disposed proximate the first end of the at least one dipole magnet. The antenna further includes a motor coupled to the shutter and configured to move the shutter between a first closed position comprising the magnetic material being positioned adjacent the first end of the dipole magnet and a second open configuration comprising the opening being positioned adjacent the first end of the dipole magnet. Alternation between the first closed position and the second open position modulates a magnetic flux emitting from the first end of the at least one dipole magnet.

In an example embodiment, systems and methods for detecting and handling faults in a DC bus system ('system') can comprise detecting a fault in the segment, isolating the segment from the system, waiting for a period of time, connecting a probe power unit to the system at the isolated segment, and determining if a fault still exists on the isolated segment, wherein the determining is based on whether power is discharging from the probe power unit when connected to the system. The system can comprise one or more controllers and a probe power unit.
