Investigation of radiation of a charged particle bunch in the presence of a large (compared with wavelengths under consideration) dielectric object can be performed using certain approximate methods. We develop here the method based on the known Stratton-Chu formulae which allows calculating the field everywhere outside the object including the Fresnel and Fraunhofer areas, as well as neighborhoods of focal points*. The main problem considered here consists in investigation of radiation of a small bunch moving along boundary of a dielectric prism or in channel inside a prism. Approximate analytical solutions of the problem are obtained and typical numerical results are given.
