acoustotreams.AcousticMaterial.krhos¶
- 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) – Angular wavenumber in the air.
kz (float or array_like) – Z-component of the wave vector. Has units of k0.
- Returns:
complex or array_like
