Optimization of Far-Field Antenna Range 

Cerny, Ondrej; Dolecek, Radovan; Kopecky, Petr; Schejbal, Vladimir; Zavodny, Vadim (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 ...

Comments on Pinched Hysteresis Loops of Memristive Elements 

Biolek, Zdenek; Biolek, Dalibor; Biolkova, Viera; Kolka, Zdenek (Společnost pro radioelektronické inženýrství, 2015-12)
The hysteresis loops pinched in the v-i origin belong to well-known fingerprints of memristive elements driven by bipolar periodical signals. Some element properties follow from the loop behavior in the close neighborhood ...
