Abstract: In this report, certain properties of the multicomponent plasmas present in the group-V semimetals As, Sb, and Bi have been derived. Notable among these properties is anisotropy of the effective masses of both electrons and holes, which in turn leads to anisotropy in the plasma frequencies of these materials. Because the systems of interest are particles in a host matrix rather than bulk materials, it is likely that this anisotropy in the plasma response will be averaged out in some way; however, this problem must be examined in detail before such a conclusion is warranted.
