### Abstract

We show that the problem of scattering of light from an achiral object in a chiral environment, which was recently studied by Lindell and Silverman [J. Opt. Soc. Am. A <b>14</b>, 79 (1997)], is merely a straightforward special case of the problem of either a chiral or a bianisotropic object in a chiral environment, solutions of which problem have existed for a while.

- Currently, some researchers think that the so-called bi-isotropic materials—which have direction-independent constitutive properties more complicated than those of chiral materials—may recognizably exist; see, e.g., R. E. Raab and A. H. Sihvola, “On the existence of linear non-reciprocal bi-isotropic (NRBI) media,” J. Phys. A Math. Gen. 30, 1335–1344 (1997). Others, including the present author, dispute that contention and have provided mathematical proofs as well. Indeed, no physical sample consistent with the Lorentz–Heaviside visualization of electromagnetic theory has ever been reported; see A. Lakhtakia, “An investigative report on the constructive [sic] relations of linear magnetoelectric media,” Int. J. Infrared Millim. Waves 15, 1363–1372 (1994); W. S. Weiglhofer and A. Lakhtakia, “On the nonexistence of linear nonreciprocal bi-isotropic (NRBI) media,” J. Phys. A Math. Gen. JPHAC5 30, 2597–2600 (1997). For the present purpose, however, it does not matter if a medium is bi-isotropic or chiral.
