For what it is worth I have found the following programs (free or low cost) to be of great assistance in dealing with the intricacies of Electromagnetic behavior in it's various forms. A great alternative to the $80,000 EM Simulator add-in for Cadence CAD systems.
"EZNEC" by Roy Lewallen (a derivative of NEC2 with a good user interface) [www.eznec.com] "TOROID" (a great aid) www.members.aol.com/toroids/johnindx.htm "SONNET-LITE" (free student version - good HF EM modeler but limited in nodes) www.sonnetusa.com "APLAC" (free student version circuit simulator) Great for digesting HF circuits www.aplac.com "RealTime" by Huan-Shang Tsai (great - low cost - 2D EM Field Simulator -ISBN 0-8493-2365-7) www.crcpress.com also of use is ARRL-"Radio Designer" (a limited - but helpful RF CAD program, ISBN 0-87259-679-6) www.arrl.org While humble compared to some "high $$$$" simulators like the offerings from ANSOFT or ZELAND, these programs provide tremendous assistance for limited (or free) cash outlay. When the marketing types force you to deal with a new product containing a TI-320 series DSP @100+ Mhz in a plastic case (read-Comb Generator), you need all the help you can get.

Antenna-to-antenna, ferrites on cables, DUT cables, BC station field strength, and such. Anyone else using NEC for this?
