function [sig_v] = volume_scatter(A, x)
%computes the volume scattering term according to Swift 1999
%Inputs:
% diel: dielectric constant
% theta: incidence angle in radians
% eta: scattering albedo
%
%Outputs:
% sig_v: volume backscatter cross-section

volume_exp = 1.2;
sig_v = A.*(cos(x).^volume_exp); %1.22 from lauren wye
