tetrascatt_c {tetrascatt}

tetrascatt_c

Description

Computes scattering from a volumetric mesh efficientlty, it is an auxiliary function called by tetrascatt function.

Usage

tetrascatt_c(cw, g, h, freq, Tet, Ver, kversor)

Arguments

cw

sound speed in the water in m/s

g

density constrast value, i.e g= rho1/rhow, where rho1 and rhow are the density values of the stcatterer and the unbounded medium respectively

h

density sound speed constrast value i.e h= c1/cw, where c1 is the sound speed of the stcatterer

freq

an array of frequencies, where the scattering is computed.

Tet

a matrix containing the four index of each tetrahedron.

Ver

a matrix with the vertex of the tetrahedra, each vertex has to have three coordinates.

kversor

three component vector that indicates the direction of the incident plane wave.

Value

A complex number array which contains the backward differential far-field scattering cross-section (f infinity) values at each frequency.
