CRIFM is abbreviation for Complex Refracive Index Functional Matrix. To take care of dissipation of light in a medium, refractivc index had been considered as complex. Light shows saturated behavior in a nonlinear medium. To take care of saturation of light in a nonlinear medium, complex refractivc index had been considered as Functional of light intensity. Light shows double refraction behavior in a anisotropic medium. To take care of double refraction of light in an anisotropic medium, complex refractivc index functional has been considered as matrix.
