Query: Sub-Wavelength Imaging and Field Mapping via EIT and Autler-Townes
  Splitting In Rydberg Atoms   We present a technique for measuring radio-frequency (RF) electric field
strengths with sub-wavelength resolution. We use Rydberg states of rubidium
atoms to probe the RF field. The RF field causes an energy splitting of the
Rydberg states via the Autler-Townes effect, and we detect the splitting via
electromagnetically induced transparency (EIT). We use this technique to
measure the electric field distribution inside a glass cylinder with applied RF
fields at 17.04 GHz and 104.77 GHz. We achieve a spatial resolution of
$\bf{\approx}$100 $\bf{\mu}$m, limited by the widths of the laser beams
utilized for the EIT spectroscopy. We numerically simulate the fields in the
glass cylinder and find good agreement with the measured fields. Our results
suggest that this technique could be applied to image fields on a small spatial
scale over a large range of frequencies, up into the sub-THz regime.
