41. Electromagnetic Fields in Cavities: Deterministic and Statistical Theories
Topic: Electromagnetics
Published: 9/21/2009
Author: David Allan Hill
Abstract: This book covers both deterministic and statistical theories of electromagnetic fields in cavities. Deterministic theory is based on resonant mode characteristics, such as quality factor, Q, and mode excitation via Dyadic Green s functions. Statist ...

42. Measurements to Support Performance Evaluation of Wireless Communications in Tunnels for Urban Search and Rescue Robots
Topic: Electromagnetics
Published: 9/4/2009
Authors: Catherine A Remley, Galen H Koepke, Dennis G Camell, George Hough
Abstract: We describe methods for evaluating the performance of the wireless link used for control and telemetry for urban search and recue robots. These methods are based on identification and evaluation of performance metrics that describe impairments to the ...

43. Integrated Broadband Lumped-Element Symmetrical-Hybrid N-way Power Dividers
Topic: Electromagnetics
Published: 6/7/2009
Authors: Mike Elsbury, Paul David Dresselhaus, Samuel Paul Benz, Zoya Popovic
Abstract: This paper presents a monolithically-integrated, broadband, lumped-element, symmetrical-hybrid power divider centered at 20 GHz which was designed and fabricated to uniformly distribute power to arrays of Josephson junctions for superconducting volta ...

Topic: Electromagnetics
Published: 6/1/2009
Authors: Dazhen Gu, Fernando Rodriquez-Morales, Sigfrid Yngvesson
Abstract: We report a coplanar waveguide notch filter with an integrated air-bridge, designed for operation at sub-millimeter wave frequencies and cryogenic temperatures. The filter is built with a planar slot- ring antenna, which is in turn loaded with a s ...

45. Uncertainty Analysis for Noise-Parameter Measurements at NIST
Topic: Electromagnetics
Published: 4/9/2009
Author: James Paul Randa
Abstract: The uncertainty analysis is presented for NIST measurements of noise parameters of amplifiers and transistors, in both connectorized (coaxial) and on-wafer environments. We treat both the X-parameters, which are based on the wave representation of t ...

46. Variable Termination Unit for Noise-Parameter Measurements
Topic: Electromagnetics
Published: 4/1/2009
Authors: Dazhen Gu, David K Walker, James Paul Randa
Abstract: NIST has upgraded its measurement capability of noise parameters on low-noise amplifiers with a variable termination unit (VTU) in the 1 to 12.4 GHz frequency range. Such a unit allows improved time efficiency and accuracy in the noise-temperature me ...

47. EEEL Technical Accomplishments
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7568
Topic: Electromagnetics
Published: 3/30/2009
Author: Erik M Secula
Abstract: This document describes the technical work of the Electronics and Electrical Engineering Laboratory. In this report, you will find that EEEL researchers are developing the world's most advanced sensors, providing advanced gamma ray imagers for astro ...

48. Electromagnetic Emissions and Performance for Proximity RFID
Topic: Electromagnetics
Published: 3/23/2009
Authors: Jeffrey R Guerrieri, David R Novotny, Michael H Francis, Catherine A Remley
Abstract: We examined the electromagnetic emissions, and performance of commercial High-Frequency (HF) proximity Radio Frequency Identification (RFID) systems including their susceptibility to jamming and eavesdropping. These proximity RFID systems are used in ...

49. Measurements of Randomly Placed Wireless Transmitters used as an Array for Receivers Located within the Array Volume with Application to Emergency Responders
Topic: Electromagnetics
Published: 3/4/2009
Authors: William F Young, Edward E. Kuester, Christopher L Holloway
Abstract: Abstract: Emergency responders often experience poor quality wireless communications due to the complex radio-frequency propagation environment encountered at a typical emergency response location, such as an apartment complex, office building, or ot ...

50. Measurements of Metamaterial-Inspired, Electrically Small Antenna Systems
Topic: Electromagnetics
Published: 3/2/2009
Authors: Christopher L Holloway, John M Ladbury, Richard Ziolkowski, Peng Jin, Chia-Ching Lin
Abstract: The paper discusses the analysis and measurements of electrical small antennas. The antennas discussed here are based on antenna designed from metamaterial inspired concepts. An electromagnetic reverberation chamber is used for the test of the antenn ...
