How can I plot admittance on the smith chart?

I am trying to make power contours on smith chart, I can make impedance graphs using commands given below but I am not able to make admittance graphs to form power contours? command to plot impedance graphs "z = 0.1*50 + 1j*(0:0.1:50); gamma = z2gamma(z); figure smithchart(gamma)"

Hello Tanveer,

MATLAB 2017a currently does not have in-built functionality to plot power contours on the smith chart directly.

I am assuming you are trying to create plots which look like (Practical RF Circuit Design for Modern Wireless Systems, Page 240, Figure 5.16): https://books.google.com/books?isbn=1580536743

Could you share any data which would help to figure out a work around?

Thank you!
