We deal with the problem of modelling a radiator/ scatterer using an equivalent radiator. The amounts at determining shape and size radiating surface producing, on region D , electromagnetic field close to that generated by primary radiator/scatterer. For fixed radiator’s shape, we here dimensi...

In steam power plants, any improvement in the cooling towers thermal performance will cause the condenser's temperature to decrease; which in turn enhances the power plant's efficiency. Due to water shortage, many power plants all around the world rely on natural draft dry cooling towers (Heller type). In these cooling towers, condenser's exit hot water is pumped to vertical or horizontal finne...

Radiators play an important role in providing a comfortable and safe indoor environment while maintaining high-energy efficiency. In the perspective of future climate change with expected larger temperature fluctuations rapidly changing heat supply demand, it is required that current radiator technology adaptable. The towards lower to enable increase energy efficiency share renewable energy. Si...

Linear vibrator and slot radiators, i.e., radiators of electric and magnetic type, respec‐ tively, are widely used as separate receiver and transmitter structures, elements of an‐ tenna systems, and antenna-feeder devices, including combined vibrator-slot structures. Widespread occurrence of such radiators is an objective prerequisite for theoretical analysis of their electrodynamic characteris...

We present measurements of the spectral distribution of transition radiation generated by electrons of momentum 1 to 10 GeV/c in different radiator types. We investigate periodic foil radiators and irregular foam and fiber materials. The transition radiation photons are detected by prototypes of the drift chambers to be used in the Transition Radiation Detector (TRD) of the ALICE experiment at ...
