Scatter Plot from Scientific Research

Calculated dispersions for the two cases denoted by the black stars in ( a ) ( C 2 / C 1 = 0.1 for ( b ) and C 2 / C 1 = 1 for ( c )). The colors denote the imaginary part of the eigenfrequencies. Circuit parameters are C = 100 nF, C 1 = 10 nF, L = 1.043 H, and R s = 30 .
