We propose a novel compensation method based on a dispersion relation equation for the constrained interpolation profile (CIP) method. In our method, two additional operations are performed after the CIP calculation. One is to calculate the numerical attenuation constant α̃ and the numerical phase constant β̃from the dispersion relation equation using Newton-Raphson method. The other is product and sum operations to compensate for amplitude and phase from the calculated α̃and the β̃. As described in this paper, both the amplitude and the phase error have been compensated using our method.
