Transmission line parameters with negative conductance loads and the "Negative" Smith chart

Neural 3-D Smith Chart

“…As seen in Fig. 2, two 2-D Smith charts standing sideby-side provides the designer to easily monitor all possible solutions including positive and negative reel part of impedance applications [6,7]. The main idea of joining left-hand side and the right-hand side charts is necessity of overlapping the same circles (also points) like r=0 circles, as given in Fig.…”

“…Zelly has proposed to use these two charts side-by-side like a mirror image to easily figure out whole domain in an attempt [6]. Lenzing et al have suggested using "negative" Smith chart first for designing one-port amplifier [7].…”
