Abstract:

A comprehensive discussion of the physics, manufacturing processes and applications of thin films in modern communications technology. The following subjects are discussed in detail 1 Structure and properties of thin films vacuum vaporization, cathode sputtering, thin film structure and physical properties. 2 Thin films as SHF load resistors peculiarities of SHF resistors, material selection, behavior in an SHF field, cylindrical disc resistors for coaxial systems, flat absorption resistors for waveguide systems. 3 Use of thin film elements for power measurement at superhigh frequencies peculiarities of such measurement, thin film bolometers, thin film thermal converters. 4 Thin film local absorbers -- absorption inserters -- for travelling wave tubes TWT local absorber requirements, local absorber design, a spiral conductive line with a coaxial cylindrical absorptive layer,experimental characteristics of thin film absorptive inserts for TWTs dependency of amplification and power of a TWT on physical parameters and location of a thin film absorptive insert, use of external absorbers to alter TWT amplitude characteristics, peculiarities of thin film local absorber production technology.
