Components Short-form Catalog Provides Solutions
Schaffner EMC, provider of EMI/RFI components, has released its new components short-form catalog with its complete line of filters, chokes, feed-through and power-quality com-ponents and pulse transformers.
The 12-page catalog offers an easy-to-use product selection chart highlighting Schaffner's extensive line of single phase and three phase products. The chart guides users to the specific product family and model number of the proper component for a specific application and provides a corresponding page number in the catalog to locate product information.

52-page EMI/RFI Shielding Products Catalog
This new catalog offers Tech-Etch's standard and custom EMI/RFI shielding product line, including all sizes, shapes, compositions, mounting options and seal types. The 52-page catalog features to-scale technical drawings, compression values and metal thickness for over 100 BeCu and stainless steel finger stock shielding profiles, including low profile gaskets, soft no-snag fingers, omni contacts, twisted contacts, strip gaskets, reverse bend, cylindrical and spherical contacts.
For ease of use, it is organized by mounting option: Track, Clip-on, Snap-on, Stick-on, Hook & Stick-on, and Special mounting. New tabs on each page make it simple to find the desired product. Finger stock gaskets are then arranged by ascending gap Free Height size to help the design engineer locate the proper gasket. Contact rings, "D" connector gaskets, board level shielding, knitted mesh shielding (with or without optional elastomer core or environmental seal), various elastomer gasket materials, fan vents, filters, honeycomb vents, plus Twinseal and Trimshield gaskets are also offered.

Video Demonstrates New EM Design Possibilities
Vector Fields has published a video exploring the potential of a radical new type of tool for optimizing electromagnetic equipment designs. The video illustrates a process that makes auto optimization possible and, within practical timescales, for almost any scale of problem, even if a user specifies several or even competing objectives.
The video starts by following the creation of a parameterized model of a quadrupole magnet for controlling particle beams. In this case the optimum design requires finding the best field shape, which depends on the length of the magnet pole tip, and the blend radius. However, even though this example problem has only one design objective, there are constraints (higher order harmonics) that need to be minimized. There are possible design solutions right across the space, so it is quite likely that manual efforts might only find a local minima.
