Detecting and Receiving Phase-Modulated Signals With a Rydberg Atom-Based Receiver

September 2, 2019
Author(s)
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon, David R. Novotny
Recently, we introduced a Rydberg-atom based mixer capable of detecting and measuring of the phase of a radio-frequency field through the electromagnetically induced transparency (EIT) and Autler-Townes (AT) effect. The ability to measure phase with this

The Interfacial Zone Around Nanoparticles in Polymer Nanocomposites

September 2, 2019
Author(s)
Jack F. Douglas, Beatriz Betancourt, Fernando Vargas-Lara, Francis W. Starr, Wengang Zhang
We perform coarse-grained simulations of model nanoparticles having a diameter on the order of 10 nm in an unentangled polymer matrix in the limit of low nanoparticle concentration to understand how the presence of nanoparticles alter the segmental

Searching for best Karatsuba recurrences

September 1, 2019
Author(s)
Cagdas Calik, Morris Dworkin, Nathan Dykas, Rene Peralta
Efficient circuits for multiplication of binary polynomials use what are known as Karatsuba recurrences. These methods divide the polynomials of size kn into k pieces of size n. Multiplication is performed by treating the factors as degree-(k-1)

The Effect of Peripheral Equipment Loading on Reverberation-Chamber Metrics

September 1, 2019
Author(s)
Anouk Hubrechsen, Laurens A. Bronckers, Kate Remley, Rob Jones, Rob Horansky, Ad Reniers, Anne Roc'h, Bart Smolders
Measuring wireless devices in a reverberation chamber often requires ancillary equipment to be present in the chamber. This paper illustrates the effect of their presence on metrics that are important in wireless device tests, such as chamber decay time

High spin-wave propagation length consistent with low damping in a metallic ferromagnet

August 31, 2019
Author(s)
L. Flacke, L. Liensberger, Matthias Althammer, Hans Huebl, Stephan Gepr?ags, Katrin Schultheiss, Aleksandr Buzdakov, T. Hula, H. Schultheiss, Eric R. Edwards, Hans Nembach, Justin Shaw, Rudolf Gross, M. Weiler
We report ultralow intrinsic magnetic damping in Co 25Fe 75 heterostructures, reaching the low 10 -4 regime at room temperature. By using a broadband ferromagnetic resonance technique in out-of-plane geometry, we extracted the dynamic magnetic properties
