EM properties of the 25-nm-thick PyC in K _a band. (a) EMI SE and |S₁₁| (b) R = |S₁₁|², T = |S₂₁|², and A = 1 − R − T. Ratios of transmitted/input (S₂₁, EMI SE) and reflected/input (S₁₁) signals measured within 26- to 37-GHz frequency range is presented in (a). Reflectivity (R), transmitivity (T) and absorptivity (A) are connected with the measured S-parameters as the following: R = | S₁₁|², T = | S₂₁|², A = 1 − R − T. Both measured and calculated values of R, T, and A are presented in (b).
