Uncertainties in Rydberg Atom-based RF E-field Measurements

October 8, 2018
Author(s)
Matthew T. Simons, Marcus D. Kautz, Joshua A. Gordon, Christopher L. Holloway
A new atom-based electric (E) field measurement approach (using Rydberg atoms) is being investigated by several groups around the world as a means to develop a new SI-traceable RF E- field standard. For this technique to be useful it is important to

MEMS non-absorbing electromagnetic power sensor employing the effect of radiation pressure

September 8, 2018
Author(s)
Ivan Ryger, Aly Artusio-Glimpse, Paul A. Williams, Gordon A. Shaw, Matt Simons, Christopher L. Holloway, John H. Lehman
We demonstrate a compact electromagnetic power sensor based on force effects of electromagnetic radiation onto a highly reflective mirror surface. Unlike the conventional power measurement approach, the photons are not absorbed and can be further used in

Development and Applications of a Fiber-Coupled Atom-Based Electric Field Probe

August 26, 2018
Author(s)
Christopher L. Holloway, Matt Simons, Josh Gordon
We are developing a fundamentally new atom-based approach for electric (E) field measurements. This new approach will lead to a self-calibrated, SI traceable, E-field measurement, and has the capability to perform measurements on a fine spatial resolution

High-resolution near-field imaging and far-fieldantenna measurements with atomic sensors

August 26, 2018
Author(s)
Christopher L. Holloway, Matt Simons, Dave Anderson, Georg Raithel
—Measurements of radio-frequency (RF) electric fields using atomic sensors based on quantum-optical spectroscopy of Rydberg states in vapors has garnered significant interest in recent years for the establishment of atomic standards for RF electric fields

Fiber-coupled Vapor Cell for a Portable Rydberg Atom-based RF Electric Field Sensor

August 1, 2018
Author(s)
Matthew T. Simons, Joshua A. Gordon, Christopher L. Holloway
We demonstrate a moveable Rydberg atom based radio frequency (RF) electric (E) field probe. The technique is based on electromagnetically-induced transparency (EIT) and Autler-Townes splitting. Two fibers attached to an 10mm cube Cs vapor cell are used to

Generalized Sheet Transition Conditions (GSTCs) for a Metascreen

May 1, 2018
Author(s)
Christopher L. Holloway
Using the multiple-scales homogenization method, we derive generalized sheet transition conditions (GSTCs) for electromagnetic fields at the surface of a metascreen---a metasurface with a ``fishnet'' structure. These surfaces are characterized by

Measurement of Radio-Frequency Radiation Pressure

February 13, 2018
Author(s)
Christopher L. Holloway, Alexandra B. Artusio-Glimpse, Matthew T. Simons, Ivan Ryger
In this work we perform measurements of the radiation pressure of a radio-frequency (RF) electromagnetic field which will lead to a new SI traceable power calibration. There are several groups around the world investigating methods to perform more direct
