The effect of the host loss on the chirality of composite chiral materials was studied by using a modified single scattering theory. Evenly distributed orientation helixes were used. Results were shown to be more efficiently obtained and more compatible with experimental measurements. The chirality parameters of five composite chiral materials with different host material loss were calculated. The calculations show that when the host loss is reduced, both the imaginary and the real parts of the chirality parameter increase very rapidly at frequencies near the resonant frequency of the embedded helixes and become narrower in bandwidth. However, only a small effect was observed for frequencies away from the resonant frequency.
