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.
