  For two electrically small nonreciprocal scatterers an analytical
electromagnetic model of polarizabilities is developed. Both particles are
bianisotropic: the so-called Tellegen-omega particle and moving-chiral
particle. Analytical results are compared to the full-wave numerical
simulations. Both models satisfy to main physical restrictions and leave no
doubts in the possibility to realize these particles experimentally. This paper
is a necessary step towards applications of nonreciprocal bianisotropic
particles such as perfect electromagnetic isolators, twist polarizers,
thin-sheet phase shifters, and other devices.
