Hello all, I'm new to the list and perhaps this may not be the proper forum for this question, but I am a signal integrity engineer and we are trying to calculate the ampacity of high-frequency transmission lines of atypical cross-sections. I'm looking for some source that would allow us to calculate temperature rise due to currents based on the Neher-McGrath equations. For example, an online Java calculator or a piece of freeware which will allow me to input resisitivity and conductor geometry. Thanks in advance, Patrick Codd Electrical Engineer Silicon Bandwidth, Inc. *************************************************************************** This message is confidential.
