Radiation by prescribed sources in a helicoidal bianisotropic medium (HBM) is investigated. The Oseen transformation and spatial Fourier transforms are used to obtain an inhomogeneous, first-order, matrix differential equation with nonconstant coefficients. As these coefficients are analytic functions of z and can be expanded as polynomials in that variable, the solution of an auxiliary homogeneous differential equation is explicitly and simply obtained. On using this auxiliary equation's solution, the radiated fields are determined and an appropriate Green function is formulated as a 4 × 4 matrix. Novel results apply to thin-film HBMs as well as to chiral liquid crystals.
