Abstract: In the present work, the non-spherical dust grain characteristics of cometLevy 1990XX with different silicate grain compositions (both pyroxene andolivine) are studied using the T-matrix method. Considering amorphous pyroxenegrain (Mg$ x$Fe$ {1-x}$SiO$ 3$) with $x$ (= 0.4, 0.5, 0.6, 0.7, 0.8, 0.95, 1)and amorphous olivine grain (Mg$ {2y}$Fe$ {2-2y}$SiO$ 4$) with $y$ (= 0.4, 0.5)(Dorschner et al. 1995), the observed polarization data of comet Levy1990XX areanalyzed using the T-matrix code at $\lambda$ = 0.485 $\mu m$.
