July 2006 [Commercial] SMD Port Discontinuities Are Conquered It was a pesky problem: the highaccuracy EM analysis of circuits with ports placed internal to the circuit (instead of on the edge). These internal ports would be used to connect surface-mount devices (SMDs) or include transistors inside an RF IC. Much of the time, uncalibrated internal port results are "good enough." When measured and calculated, they line up reasonably close. But there was that pesky little bit of difference that occasionally became large and design-disabling. ... February 2003 [Computer-Aided Engineering] Electromagnetic Analysis Speeds RFID Design Radio-frequency identification (RFID) is one of the fast-growing wireless market segments. Strong competition among RFID suppliers, however, requires fast product design times and rapid time to market. Fortunately, fast and accurate electromagnetic... |
