A dielectric waveguide ferrite resonance isolator capable of operating in the 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 heat sink thereby extracting heat from the hexagonal ferrite.
