A portable wireless device for recharging batteries of vehicles is described in this paper. Application of novel, based on coupled radial spirals antennas with dimensions significantly less than the operating wavelength in free space, makes it possible effective pumping of RF energy without radiation into surrounding medium.
A sensor for detecting plastic explosives placed in the ground is presented in this paper. The detection effect is based on the intensive radiation from the section of a slow-wave structure at slowing down less than slowing of the light in the medium, i.e. in the soil at the place of possible laying of the mines. High effectiveness and small dimensions in comparison to the wavelength in free space and possibility of monitoring at a wide frequency band define its significant advantages in comparison to another devices for detecting explosives.
Problems of the even temperature distribution creation in the volumetric materials with different dielectric losses placed in the beam-type microwave device are examined. The volumetric material was irradiated by two types of antennas which provided perpendicular and parallel flux direction of the electric-field vector relatively to the material’s surface. Experimental data on the temperature field distribution in the volume of material is presented. It is shown that the total temperature dispersion is less than 5ºC inside the material heated up to 80ºC.
