ABSTRACT:
A dielectric waveguide ferrite resonance isolator capable of operating in e millimeter wave frequency range in a dielectric waveguide transmission line in which a thin rectangular hexagonal ferrite material is affixed to a side of the dielectric waveguide and then placed between the pole pieces of an electromagnet in order to magnitize and fully orient the ferrite material is improved by positioning a grooved block of dielectric having a low dielectric constant and high thermal conductivity against the face of the hexagonal ferrite so as to use the high thermal conductivity dielectric as a heat sink thereby extracting heat from the hexagonal ferrite.
