The idea of a training and research laboratory was proposed in April 2013. And documented in January 2014. The main proposes of the laboratory are organization and conduction of theoretical and experimental scientific research in the field of radiophysics and electronics. Particular attention is paid to works that are focused on the development of millimeter and submillimeter-range technologies. At the present time, serious attention is being devoted to the development of diffraction type antennas, which are promising for creating both radio-active, active and passive radar systems and communication systems that will ensure the functioning of 5G technology. Below are illustrative materials on the systems and devices created in the last 3 years. In addition, the reports of prof. Vertii A. prof. Sirenko Y. give information of the main publications made for their period of time.
One of the key tasks in the reporting period was the creation of a laboratory and technological base to support the research and application programs of the laboratory. Below is a brief description of the new areas that have developed over the reporting period. New ideas and their practical implementation.

DEVICE OF MILLIMETER RANGE FOR DETECTING HAZARDOUS (DANGEROUS) LIQUIDS
Surface wave method
In the method we propose, detection takes place using an open electrodynamic system consisting of a radiation source in the millimeter wavelength range, an open dielectric waveguide (DW), and a detector.
Figure 1 shows the electrodynamic scheme of the detection process, in which the object of analysis is the tested plastic (glass) bottle 1, located in the immediate vicinity of the DW2.

RADIOMETRICS OF MILLIMETER RANGE WAVE (MICROWAVE) LENGTH
In 2015-2016, active work continued on the development of the laboratory infrastructure. Particular attention was paid to antenna problems. An experimental installation was created for investigating the near fields of mirror antennas.
One of the first applications of such a facility was the study of a radiometric system of millimeter wavelengths (mm). The diameter of the aperture of the antenna system was 1500 mm. It was created for using in radio image forming systems to detect hidden objects.
