Love-wave dispersion benchmark

Phase velocity, group velocity, and propagation-Q benchmark against the analytical solution.

Love-wave phase kernels

Phase-velocity sensitivity kernels compared with the analytical solution.

Love-wave group kernels

Group-velocity sensitivity kernels compared with the analytical solution.

Coupled fluid/solid Scholte-wave model

Layer	Thickness (km)	\(\rho\) (g/cm³)	\(V_P\) (km/s)	\(V_S\) (km/s)
Fluid	5	1.00	1.50	0.00
Solid 1	45	2.57	5.22	3.10
Solid 2	50	2.95	6.94	4.00
Half-space	\(\infty\)	3.57	8.75	5.00

Scholte-wave dispersion

Phase and group velocity benchmark against CPS330.

Scholte-wave eigenfunctions

Normalized coupled solid displacement and acoustic-potential eigenfunctions.

Scholte-wave phase kernels

Phase kernels compared with centred finite differences.

Scholte-wave group kernels

Group kernels compared with centred finite differences.

The test suite also covers attenuating fully anisotropic group velocity, radial/x/y group-kernel consistency, and coupled acoustic bulk-modulus group kernels. These checks use the same analytic frequency and model derivatives as the production solver.
