Query: A split-cavity design for the incorporation of a DC bias in a 3D
  microwave cavity   We report on a technique for applying a DC bias in a 3D microwave cavity. We
achieve this by isolating the two halves of the cavity with a dielectric and
directly using them as DC electrodes. As a proof of concept, we embed a
variable capacitance diode in the cavity and tune the resonant frequency with a
DC voltage, demonstrating the incorporation of a DC bias into the 3D cavity
with no measurable change in its quality factor at room temperature. We also
characterize the architecture at millikelvin temperatures and show that the
split cavity design maintains a quality factor $Q_\text{i} \sim 8.8 \times
10^5$, making it promising for future quantum applications.
