- EMI, RFI, and ESD products. Buchanan, Betsy // ECN: Electronic Component News;Apr98, Vol. 42 Issue 4, p95
Looks at some additions to the electromagnetic compatibility marketplace in the United States. Includes Rubbercraft Corp.'s conductive elastomers; Wieland Electric's grounding clamp; Amplifier Research's compact interference generators; Hewlett-Packard's software.
- H- beam extraction experiments on the Culham small multipole source. McAdams, R.; Holmes, A. J. T.; Nightingale, M. P. S. // Review of Scientific Instruments;Jun88, Vol. 59 Issue 6, p895
Beam extraction experiments have been carried out on a multicusp volume H- ion source operated in a dc mode. With an extraction aperture of 16-mm diameter, negative ion beams of up to 15 mA cm-2 have been extracted. Some experiments have been performed to investigate the physics of beam...
- Development of the electromagnetically launched expanding ring as a high-strain-rate test technique. Gourdin, W. H.; Weinland, S. L.; Boling, R. M. // Review of Scientific Instruments;Mar89, Vol. 60 Issue 3, p427
Improvements to the electromagnetically launched expanding ring experiment that make the technique more reproducible, analyzable, and amenable to the rapid testing of many specimens are presented. Aspects of the design and containment of the primary solenoid, high-voltage switching, and...
- Reflectivity of planar metallic fractal patterns. Zhou, Lei; Wen, Weijia; Chan, C. T.; Sheng, Ping // Applied Physics Letters;2/17/2003, Vol. 82 Issue 7, p1012
We studied the reflective properties of a small dielectric plate covered with a fractal-like metallic pattern generated by a particular type of space-filling curves. We found, both experimentally and theoretically, that the plate can reflect electromagnetic waves in a multitude of frequencies,...
- A Unique Way to Keep Secrets. // Boys' Quest;Oct/Nov2000, Vol. 6 Issue 3, p13
Presents information on how to make an electromagnetic secret drawer lock in the house.
- Electromagnetic showers in oriented garnet crystals. Baskov, V. A.; Bugorskii, A. P.; Vasil�ev, A. N.; Kim, V. V.; Luchkov, B. I.; Meshchanin, A. P.; Mysnik, A. I.; Polyanskii, V. V.; Sergienko, V. I.; Tugaenko, V. Yu.; Khablo, V. A. // Technical Physics Letters;Jun98, Vol. 24 Issue 6, p439
The orientation dependences of the energy release in showers formed in transparent garnet crystals with thicknesses of 23 and 50 mm are measured, and the influence of the orientation of the crystals on the absorption of a shower in an amorphous radiator is determined.
- Electromagnetic sensors put a spin on compasses. Travis, Bill // EDN;3/14/96, Vol. 41 Issue 6, p77
Describes the technologies used for electromagnetic sensors that were designed to replace the magnetized-needle compass technology. Operating theory of Hall-effect devices; Flux-gate sensors available from Applied Physics Systems; Permalloy-based magnetoresistive sensors; Typical three-axis...
- Dynamic Error Analysis of Ascension's Flock of Birds� Electromagnetic Tracking Device Using a Pendulum Model. McQuade, Kevin J.; Finley, Margaret A.; Harris-Love, Michelle; McCombe-Waller, Sandra // Journal of Applied Biomechanics;May2002, Vol. 18 Issue 2, p171
The use of magnetic tracking technology has become increasingly popular in recent years for human motion studies. However, there have been few independent evaluations of how these systems perform. The purpose of this study was to develop a dynamic pendulum calibration method to test the...
- E-BOMB. Wilson, Jim // Popular Mechanics;Sep2001, Vol. 178 Issue 9, p50
Warns against the danger of electromagnetic bombs (E-bombs). Damage that could be caused by e-bombs; Details on the test of an E-bomb in the United States; Cost of building a basic E-bomb; Theory behind the E-bomb.
