New approaches to calculate the optical properties of small nonspherical layered particles whose layer boundaries are nonconfocal concentric coaxial ellipsoids are considered. A simple analytical approximation is suggested and substantiated for the case when the size of similar layer particles is much less than the wavelength of the incident radiation. It is found that this approximation provides the results with the accuracy of about 0.003 when the diffraction parameter x < 0.1. An approach to calculate the optical properties of nonconfocal ellipsoids by using a substitute of the nonconfocal boundaries with the confocal ones with keeping the layer volumes constant is justified. It is shown that for dielectric particles such an approach has the accuracy of a few percent for x < 1 and about 20% for x < 5. It is noted that both approximations are easily expanded on the case of multilayered nonconfocal ellipsoids.
