Scattering coefficient of the brain tissue was modelled by [[mu]'.sub.s] = a[([lambda]/500nm).sup.-b], where[lambda] is the excitation or emission wavelength and a is a scaling factor which represents the reduced

scattering coefficient at [lambda] = 500nm.

where [g.sup.m.sub.n,TM] and [g.sup.m.sub.n,TE] are the generalized functions of GLMT, an and bn are the

scattering coefficient of Mie theory, and E and H are the magnetic and electric energy.

where [I.sub.[lambda]](x, [OMEGA]) is the spectral radiation intensity, [lambda] represents the wavelength, [[beta].sub.[lambda]] is the extinction coefficient, which is the sum of the absorption coefficient, [[kappa].sub.[lambda]], and [[sigma].sub.[lambda]] is the

scattering coefficient. The ratio [omega] = [[sigma].sub.[lambda]]/[[beta].sub.[lambda]] is the scattering albedo coefficient which is inherent to each photocatalyst since it represents its photon absorption capacity.

Assuming that biological cells are approximate to homogeneous spherical particles, the

scattering coefficient [Q.sub.sca] is computed from the rigorous Mie theory as given by [32]:

Thanks to this, the RBCs have a strong mismatch in refractive index and the

scattering coefficient of the RBC is almost 1000 times larger than the

scattering coefficient for any other blood particle.

1, the so called '

scattering coefficient' [gamma] at an arbitrary scattering direction ([[theta].sub.2], [[theta].sub.3]), which represents the scattered electric field at that direction normalized by the scattered electric field at the so--called 'specular direction', i.e.

The composite scattering characteristics can be evaluated by the

scattering coefficient, as defined by

The absorption coefficient is denoted by [[mu].sub.a] (x), and the

scattering coefficient is denoted by [[mu].sub.s] (x).
