AcousticMaterial.krhos(k0, kz)[source]

The (cylindrically) radial part of the wave vector for longitudinal waves .

The cylindrically radial part is defined by \(k_\rho = \sqrt(k^2 - k_z^2)\). The returned values have non-negative imaginary parts.

Parameters:

  • k0 (float) – Wave number in air.

  • kz (float, array-like) – z-component of the wave vector

Returns:

complex, array-like
