The article presents the results of a comprehensive theoretical and experimental study of ferromagnetic resonance and microwave magnetoelectric effect in multilayer ferrite-piezoelectric structures containing single-crystal iron-yttrium garnet of cut (111) in combination with piezoelectric materials. Mathematical modeling of physical processes occurring in ferrite was performed, which made it possible to reveal weak magnetic cubic anisotropy, which must be taken into account when developing electrically tunable microwave devices.

The article presents the results of an experimental study of the absorption properties of carbon nanostructured films in the S-band. The dependence of the transmission, reflection and absorption coefficients on the resistance of carbon samples with an absorption peak of an incident electromagnetic wave in the resistance range of 350–400 Ohm is shown.

This study is based on the analysis of the current state and main trends in the design, synthesis and application of various transparent electrodes, including transparent conductive semiconductor oxides, metal ultrathin films, partially filled structures and multilayer oxide/metal/oxide structures.

A computational experiment has been performed in order to evaluate systematic errors of atmospheric Total Water Vapor (TWV) and integral Liquid Water Content (LWC) microwave radiometric retrieval from satellites by means of dual-frequency method (inverse problem).  The errors under consideration may arise due to the non-linearity of brightness temperature level on true liquid water and effective cloud temperature dependencies and due to neglecting the spatial distribution of cumulus clouds in the satellite microwave radiometer antenna field-of-view (FOV).

This dataset contains approx. 5000 labeled images of marker on Smith Chart of Keysight VNA 9914a. Since smith chart contains "infinity" (although compensated in the device mathematically), the data from Smith Chart window pane is not apt for tuning the all-pole MW filters.

This dataset can be used to track the marker position while tuning the circuitary when considering Image Processing based Filter Tuning. Images are taken from various angles to ensure the robust behaviour and high detection accuracy. 

The proposed signals are used  for electromagnetic-based stroke classification.  Six realistic head phantom computed from MRI scans, is surrounded by an antenna array of 16 dipole antennas distributed uniformly around the head. These antennas are deployed in a fixed circular array around the head, at a distance of approximately 2-3 mm from the head.
