Cecil, you've proven over and over again that you're not interested in technical discussion. Allow me to disprove your opinion of me. Please respond to this earlier posting of mine: The testx.EZ file has been renamed to: http://www.qsl.net/w5dxp/TravWave.EZ The testy.EZ file has been renamed to: http://www.qsl.net/w5dxp/StndWave.EZ The current reported by EZNEC for TravWave.EZ contains the term cos(kz+wt) It's a traveling wave current, clearly not the same as a standing wave current. The current reported by EZNEC for StndWave.EZ contains the terms cos(kz)*cos(wt) It's a standing wave current, clearly not the same as a traveling wave current. Current reported by EZNEC every 10% of wire #2 is presented in the following table. The currents are obviously very different. The phase of the traveling wave progresses from 0 to 90 deg in 90 deg of wire. The phase of the standing wave doesn't progress beyond 0.11 of of degree. % along current in current in wire #2 TravWave.EZ StndWave.EZ 0% 0.9998 at -0.99 deg 0.9996 at 0 deg 10% 0.9983 at -9.39 deg 0.9843 at -0.03 deg 20% 0.9969 at -18.23 deg 0.9454 at -0.05 deg 30% 0.9957 at -27.59 deg 0.8843 at -0.06 deg 40% 0.9949 at -35.96 deg 0.8023 at -0.08 deg 50% 0.9945 at -44.84 deg 0.7014 at -0.09 deg 60% 0.9945 at -54.20 deg 0.5840 at -0.09 deg 70% 0.9949 at -62.58 deg 0.4528 at -0.10 deg 80% 0.9956 at -71.43 deg 0.3110 at -0.11 deg 90% 0.9965 at -80.27 deg 0.1616 at -0.11 deg 100% 0.9976 at -89.14 deg 0.0061 at -0.11 deg Some say "current is current". EZNEC disagrees. When reflected waves are eliminated, EZNEC indeed does accurately report traveling wave current. EZNEC reports the current that is there, whether it is traveling wave current or standing wave current. -- 73, Cecil http://www.qsl.net/w5dxp |
