Meeting Announcement:
Santa Clara Valley Chapter of IEEE EMC Society Meeting Scott Bennett: "The Physics of Electromagnetics Without Abstract Mathematics" Tuesday, January 9, 2001 The January meeting of the Santa Clara Valley EMC Society will be held at SGI in Mountain View, 1600 Amphitheatre Pkwy., building 40, in the Presentation Center above the lobby. The social gathering will start at 5:30 PM, and food and drinks will be available. The technical presentation will start at 7:30 PM. A map with the location of the SGI campus is available at the Santa Clara Valley web site www.scvemc.org . Abstract : The basic point source of electromagnetic fields -- the charge element -- is derived and described with basic physics and high-school mathematics. The charge element is a simpler point source than the current element -- it has five field components, whereas the current element has seven -- yet these two basic field sources are shown to be equivalent. The physical causes of the two H-field and three E-field components of the charge element are easily explained, and they are kept obvious with the descriptions derived for those components. Simple examples are then given to show how to use charge elements to better understand the fields of full-size currents, and the physical origins of those fields. Regards, Neven Pischl
