FIELD: home appliances.

SUBSTANCE: invention relates to microwave devices. Waveguide comprises elongated dielectric inner area and electrically conducting outer region separated from dielectric inner area. Dielectric inner area can be made so that it is flexible, and in some versions can be made of dielectric powder contained in polymer tube or in matrix, or in other examples may be formed from plurality of segments. In some versions of waveguide each segment may be formed so that it has lenticular end surfaces, and can be formed from sintered BaTi₄O₉.
