Understanding of operation principles and development of the most part of the dielectric element base (DEB) used at present for construction of an increasing number of various passive components for the millimeter wave range has begun from examination of dielectric waveguides (DWG). To date, other types of dielectric structures (DS) are included into DEB besides DWG: resonators, functional devices...
The article describes the design and operation of waveguide-beam transducers in EHF-band provided in the dielectric element base and multimode dielectric waveguides. The main object is wide-dimensional dielectric waveguides. The phenomena, which have place in wide-dimensional dielectric waveguides, are analyzed. The ways to improve efficiency and quality of waveguide-beam transducers are suggested.
After twenty-five years of study on Saturn electrostatic discharges (SED) with the aid of spacecrafts (Voyager I, II, Cassini) the first successful ground-based observations with radio telescopes UTR-2 were carried out. The result was unambiguous registration of 70 events by ground-based instrument during the storm E, which lasted about a month in January-February 2006. This work presents the observation...
Thin film electroluminescent (TFEL) structures have been under development as a basis of many significant new devices such as full color displays. The hypermodelling for TFEL display properties was proposed. A basis of the approach proposed is a mathematical modelling of the TFEL structures, electric and optical characteristics together with the analysis of features of their functioning in the schematics...
