"Smith chart has a circular impedance and admittance grid of intersecting resistance and reactance curves. The horizontal resistance scale includes values 0, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, and 50. Curved reactance scales extend above and below the center line, with values including 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, and 50. Perimeter scales indicate wavelength and reflection parameters."
