QuickField Webinar: Electromagnetic Shielding: Part 3/5

QuickField for Electromagnetic Shielding Applications. This free webinar was held on June 14, 2011 at www.quickfield.com.
The speaker and the author is Dr. James Claycomb who recently spoke about biophysical simulations. The use of QuickField for shielding low frequency AC, static, and electromagnetic noise sources will be modeled. Examples include power line (50 or 60 Hz and harmonics), the geomagnetic field and its variations, lightning, stray fields from electric motors, and electromagnetic pulse (EMP) resulting from nuclear detonation. The shielding properties of various conducting, permeable and superconducting material combinations will be demonstrated.

Part 3. Magnetically shielded rooms, to shield low-frequency field: Single layer (copper), Multi layer (copper + mumetal), Doors and outlets. AC magnetics problem, axis symmetrical. Modeling gaps. Serial analysis with LabelMover to find the better design. Calculation of iterative modeling problems. Flux density in shielded rooms with and without a gap opening.
