The emission of electromagnetic waves by a straight edge dislocation moving in an ionic crystal with a NaCl-type lattice was investigated. It was shown that the motion of the dislocation resulted in the appearance of a polarization current which was generated by uncompensated valence bonds along the edge of the extra plane of the dislocation. For a dislocation moving with a constant average velocity, V, the frequency of the current was of the order of 2πV/b; where b was the Burgers vector. The far-field flux of electromagnetic energy, and the radiation friction force which acted per unit length of dislocation line, were calculated. The emission of electromagnetic waves by an edge dislocation which oscillated on the glide plane, and by a constantly accelerating dislocation, was also studied.
