ABSTRACT:
The invention relates to electromagnetic wave guiding devices or waveguides (f<10 THz) and to processes for manufacturing these waveguides, which comprise at least one body (30) supporting at least one active wall (40). The body (30) of the waveguide is made from a volume of a ceramic selected from the following: silicon carbides, aluminum nitride, boron nitrides, and especially 3C cubic and 2H hexagonal varieties of boron nitride, diamond, beryllium oxide or assemblies of said materials. Applications: waveguides, filter cavities, reflectors and antennas for radiofrequency waves and microwaves, atomic clocks and particle accelerators.
