This is an Editorial for the August, 2009 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

High Definition Flow

August 1, 2009
Author(s)
John D. Wright, Michael R. Moldover
From pharmaceutical production to the natural gas market, exact flow measurements are critical. Here's how NIST helps keep us all on the same page.

MEMS in Action: RoboCup Nanogram 2009

August 1, 2009
Author(s)
Richard A. Allen, Craig D. McGray
From June 29 through July 5, 2009 teams from around the world participated in the International RoboCup competition, held in Graz, Austria. In addition to humanoid robots playing soccer on turf fields, companion robots demonstrating their ability to help

Radiation-Based Quantitative Bioimaging at NIST

August 1, 2009
Author(s)
Lisa R. Karam
The National Institute of Standards and Technology (NIST) provides the physical measurements and standards in a variety of fields, including for ionizing radiation, for the US. Building on a long history of providing standards for medical x rays and

Stylus ion trap for enhanced access and sensing

August 1, 2009
Author(s)
Robert Maiwald, Gerd Leuchs, Dietrich Leibfried, Joseph W. Britton, James C. Bergquist, David J. Wineland
We experimentally characterized a novel radio-frequency (rf) ion trap geometry formed by two concentric cylinders over a ground plane. These traps allow for optical and physical access over more than 2 pi solid angle reaching 91% and 96% of 4 respectively

Towards portable vacuum standards

August 1, 2009
Author(s)
Jay H. Hendricks, Douglas A. Olson
Since the middle of the 17th century, when Italian physicist Evangelista Torricelli discovered that a glass tube filled with mercury could be used to measure atmospheric pressure, liquid-column manometers have been used as a primary standard to measure

Recent developments in large-scale dimensional metrology

July 30, 2009
Author(s)
G Peggs, P.G Maropoulos, E.B Hughes, Alistair Forbes, S Robson, M Ziebart, Bala Muralikrishnan
With ever-more demanding requirements for the accurate manufacture of large components, dimensional measuring techniques are becoming progressively more sophisticated. This review describes some of the more recently-developed techniques and the state-of

Symbol Representing Biometrics in Use

July 30, 2009
Author(s)
Yee-Yin Choong, Mary Theofanos, Brian Stanton
During the InterNational Committee for Information Technology Standards (INCITS) M1 task group meetings in 2008, it was recognized that there is a need for a symbol to represent that any biometrics (fingerprint, iris, photo, etc.) are in use. The symbol is

Measurement and Standards: The role of NIST

July 29, 2009
Author(s)
Kent B. Rochford
At NIST, said Dr. Rochford, "we are very broad, but we focus like a laser on measurement science." NIST also helps develop standards and promote technology. He called the institute "fairly small," with about 2,800 employees and almost that many affiliated

Overview of MSA Needs for Homeland Security

July 29, 2009
Author(s)
Charles R. McLean, Sanjay Jain, Yung-Tsun Lee
A number of modeling, simulation and analysis (MSA) efforts have evolved to support homeland security initiatives. Various organizations involved in homeland security related work have realized the value of MSA and have funded development for their

System Testing Using Use Cases for an ER Simulation Model

July 29, 2009
Author(s)
Guodong Shao
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. It is particularly useful for Department of Homeland Security (DHS) applications because of its feature of non
