  The cosmological axions/axion-like particles can compose a significant part
of dark matter, however the uncertainty of their mass is large. Here we propose
to search the axions using a cylindrical capacitor, in which the static
electric field converts dark matter axions into an oscillating magnetic field.
Using a static electric field can greatly reduce the magnetic field background
compared to using the $\vec B$ field that the thermal current in the
magnet-coil could be hard to annihilate. A cylindrical setup shields the
electric field to the laboratory as well as encompasses the axion induced
magnetic field within the capacitor, which results an increased magnetic field
strength. The induced oscillating magnetic field then can be picked up by a
SQUID-based magnetic-meter. Adding a superconductor ring-coil system into the
induced magnetic field region can further boost the sensitivity and maintain
the axion dark matter inherent bandwidth. The proposed setup is capable of a
wide mass range searches as the signal can also be modulated by adjusting the
angle between the electric field and the axion flow.
