摘要：
A chiral smectic liquid crystal is considered, made of elongated molecules whose directions describe a helix along a given direction. It is shown that for small values of the helix pitch it behaves as a homogeneous medium which is optically active and uniaxial, with maximum rotatory power for light propagating orthogonally to the helix axis. Analytic expressions are given to describe the gyrotropic properties of the medium. The analogies with other helical-shaped structures are discussed.
