  • Optimization of Far-Field Antenna Range 

    Cerny, O.; Dolecek, R.; Kopecky, P.; Schejbal, V.; Zavodny, V. (Společnost pro radioelektronické inženýrství, 2015-12)
    Measurements of test antennas are performed on antenna ranges. The operated microwave far-field outdoor range was built-up in 1970’s and therefore it was not appropriate for the today measurements. Thus, it was decided to ...

  • Tropospheric Propagation above Uneven Ground 

    Schejbal, V.; Zavodny, V. (Společnost pro radioelektronické inženýrství, 2017-12)
    This work analyzes the electromagnetic wave propagation above uneven ground, including the troposphere, using physical optics calculation. The new results of numerical simulations using physical optics are presented for ...

  • Two-Dimensional Forward Scattering – Comparisons of Approximate and Exact Solutions 

    Schejbal, V.; Svoboda, P.; Pidanic, J.; Fiser, O. (Společnost pro radioelektronické inženýrství, 2012-04)
    Various methods for analyses of scattering are mentioned and new approximate relationships are derived. Experimental results for thin wire and several numerical simulations of forward scattering using approximate estimations, ...
