Forerunners (precursors) in linear, temporally dispersive, bigyrotropic materials are investigated with time -domain techniques. Bigyrotropic materials are characterized by 12 constitutive parameters (integral kernels). Specifically, the four susceptibility dyadics are all gyrotropic with a common gyrotropic axis. Pulse propagation along this axis is analyzed with dispersive (noncoupling) wave splitting and complex, time-dependent field vectors. Two numerical examples illustrating the method are presented. # 1998 Optical Society of America [S0740-3232(98)02909-3] 0CIS codes: 260.1180, 260.2030, 320.5550.
