review text: The boundary perturbation method developed in part I [see the summary above (Zbl 0602.73118)] is applied to investigate asymmetric radiation due to oscillating dislocations in solids. For an eccentrically located dislocation in a circular cylinder, the response is found to be in agreement with the exact solution. The response to dislocations oscillating about the centre of an elliptic cylinder is obtained and reveals a frequency spectrum markedly different from that of a circular cylinder.
