Abstract :
We were the first to report for printed-circuit transmission lines that nonphysical improper real solutions have significant effect on physical total field excited by a practical source. We have recently studied such interesting and unexpected effects in more detail, and we have discovered here that nonphysical leaky solution also causes a significant effect on physical near field excited by a practical source, contrary to earlier belief.
