powerLawKramersKronig
Calculate dispersion for power law absorption.
Syntax
c_kk = powerLawKramersKronig(w, w0, c0, a0, y)
Description
powerLawKramersKronig computes the variation in sound speed for an attenuating medium using the Kramers-Kronig for power law attenuation where att = a0*w^y. The power law parameters must be in Nepers / m, with the frequency in rad/s. The variation is given about the sound speed c0 at a reference frequency w0.
Inputs
w |
input frequency array [rad/s] |
w0 |
reference frequency [rad/s] |
c0 |
sound speed at w0 [m/s] |
a0 |
power law coefficient [Nepers/((rad/s)^y m)] |
y |
power law exponent, where 0 < y < 3 |
Outputs
c_kk |
variation of sound speed with w [m/s] |
