Abstract :
The complex dielectric permittivity properties of lossy ceramic materials used in vacuum electronics are presented. The studies include broadband room temperature behavior in the 0.1-18 GHz range and in W-Band (75-110 GHz). Variable temperature measurements of selected materials at 94 GHz are also presented
