Abstract :
A new kind of coherent radiation induced by uniformly moving charge is introduced. It appears as a wavepacket forerunning ahead of the charge. It was derived as a complementary case of existing theory of resonant wakefield extended to include the exotic "overturned wake" affected by the leading front distortions due to dispersion. Corresponding conditions, causality and potential realizations in special types of slow-wave systems are analyzed and discussed. Those can include moving media and metamaterials, plasma and some of periodic structures.
