Nickel films of 4–250 nm thickness were produced by DC magnetron sputtering onto glass and silicon substrates. The electrical properties of the films were investigated by the four-probe method and the surface morphology of the films was studied by atomic force microscopy. To measure the shielding effectiveness, a portable closed stand based on horn antennas was used. A theoretical assessment of the shielding effectiveness of nickel films of various thickness under electromagnetic radiation of a range of frequencies was carried out using two different approximations. The results demonstrate the shielding effectiveness of up to 35 dB of the nickel thin films in the frequency range of 2–18 GHz.

A general theory describing the dispersion of surface spin waves has been developed for ferrite-dielectric-metal multilayered structures that takes into account the finite values of the layer permittivity and conductivity. The influence of different structure parameters on the dispersion characteristics was analyzed. A change of the conductivity of the conducting film layer manifests itself in a strong wavenumber variation. A novel miniature spin-wave phase shifter based on ferrite-dielectric-vanadium dioxide multilayered structures is proposed. A structure 1 mm in length gives a phase shift of 5.27 rad and an insertion loss of 2.1 dB at a frequency of 8.99 GHz. The introduction of a dielectric layer between the ferrite and vanadium dioxide films preserves the wavenumber variation and minimizes the thermal effect induced by heating of the vanadium dioxide film.

A discharge in a planar magnetron with a titanium target is studied. It is found that a pressure rise from 2 to 6 mTorr in argon at a constant current increases the intensity of excited argon ion lines by almost 20%. The excitation of neutral titanium atoms is independent of the argon pressure: it depends on only the discharge current. The current-voltage characteristic of the magnetron in an argon-oxygen mixture completely reflects processes proceeding on the target of the magnetron.

The split-cylinder resonator method was adapted to measure the microwave properties (dielectric permittivity and loss tangent) of thin ferroelectric films on a dielectric substrate. The mathematical model for calculating the resonance frequency of the split-cylinder resonator was adjusted for the “ferroelectric film—substrate” structure. An approach for correcting the gap effect based on calibrating with a single-layer dielectric was introduced and used to study two-layer dielectrics. The prototype of a split-cylinder resonator designed to measure single-layer dielectric plates at a frequency of 10 GHz was presented. The resonator calibration was performed using dielectric PTFE samples and fused silica, and an example of the correction function was suggested. The measurement error was estimated, and recommendations on the acceptable parameter range for the material under investigation were provided. The method was demonstrated to measure the microwave properties of a ferroelectric film on a fused silica substrate.
