Measurement of Shielding Effectiveness of Electrically-Small Enclosures

August 13, 2011
Christopher L. Holloway, Colton R. Dunlap, John M. Ladbury, Joshua A. Gordon, Jason B. Coder, Galen H. Koepke
In the following we propose a technique for determining the shielding effectiveness (SE) an electrically small enclosure. In particular, we use this technique to explore the shielding characteristics of a rectangular box used to shield a satellite based

Fluid interactions with metafilm/metasurfaces for tuning, sensing, and microwave assisted chemical processes

May 25, 2011
Joshua A. Gordon, Christopher L. Holloway, James C. Booth, James R. Baker-Jarvis, David R. Novotny, Sung Kim, Yu Y. Wang
In this paper we demonstrate tunability of a metafilm, which is the two-dimensional equivalent of a metamaterial, also referred to as a metasurface, by changing the permittivity in a micro-fluidic channel that interacts with the metafilm. Numerical

Quantum-Based SI Traceable Electric-Field Probe

July 25, 2010
Joshua A. Gordon, Christopher L. Holloway, Steven R. Jefferts, Thomas P. Heavner
We are presently investigating the feasibility of developing a technique that will allow direct traceable microwave electric field (E-field) measurements. The new approach is based on atomic rf-resonance spectroscopy, where an applied electrical field
