Resonant microwave power absorption and relaxation of the energy levels of the molecular nanomagnet Fe 8 using superconducting quantum interference device-based magnetometry

August 15, 2005
Author(s)
Brant Cage, Stephen E. Russek, David Zipse, Micah North, Naresh S. Dalal
Energy levels and saturation of molecular nanomagnet Fe 8 crystals were investigated using a 95 and 141 GHz electron paramagnetic resonance (EPR) technique based on a standard superconducting quantum intererence device (SQUID) magnetometer. The technique

A Complete Multimode Equivalent-Circuit Theory for Electrical Design

June 22, 1999
Author(s)
Dylan F. Williams, L. A. Hayden, Roger Marks
This work presents a complete equivalent-circuit theory for lossy multimode transmission lines. Its voltages and currents are based on general linear combinations of standard normalized modal voltages and currents. The theory includes new expressions for

Fire Resistance of Structural Members and Assemblies

March 1, 2023
Author(s)
Matthew Hoehler
The selection of building materials and the design of the details of construction always play an important role in overall building fire safety. Two important fire safety considerations regarding the building structure are to minimize the likelihood of

Effect of Local Oscillator Performance on UWB Based Indoor Localization System

May 21, 2018
Author(s)
Archita Hati, Fabio C. Da Silva, Vladislav P. Gerginov, Craig W. Nelson
We discuss the performance of a commercial Ultra-wideband (UWB) ranging technique for indoor localization. We study the influence of local oscillator's phase noise and its frequency drifts due to temperature variations on the range estimation and ranging
