The topic of converstaion was: Poynting Vector Energy Anaylsis of An Impedance Discontinuity. Yes it was. So what happens to the reflected power Poynting Vector (that the above reference says exists) when it encounters the impedance discontinuity? 100W source--50 ohm feedline--+--1/2WL 150 ohm feedline--50 ohm load The reflected power Poynting vector on the left side of the impedance discontinuity is zero. The reflected power Poynting vector on the right side of the impedance discontinuity is 33.33W pointing toward the left. For about the tenth time, what happens to that reflected power Poynting vector? |
