The least upper bounds of the powers extracted and
scattered by bi-anisotropic particles are investigated analytically.
A rigorous derivation for particles having invertible polarizability
tensors is presented, and the particles with singular polarizability
tensors that have been reported in the literature are treated
explicitly. The analysis concludes that previous upper bounds
presented for isotropic particles can be extrapolated to bianisotropic
particles. In particular, it is shown that neither nonreciprocal
nor magnetoelectric coupling phenomena can further
increase those upper bounds on the extracted and scattered
powers. The outcomes are illustrated further with approximate
circuit model examples of two dipole antennas connected via a
generic lossless network. [--]
